The CSS image() function is designed to make image values more flexible by letting authors declare an image source with optional fallbacks, direction-aware alternatives, and even a solid color if no usable image can be rendered.
It can be used anywhere an <image> value is accepted, such as background-image, but its real value comes from safer asset handling: you can provide a preferred image, account for left-to-right or right-to-left layouts, and define what should appear when support or loading fails.
Because browser support is still limited compared with widely used functions like url() and image-set(), image() is best approached with progressive enhancement, fallback declarations, and careful testing in the browsers your project supports.
What the image() Function Does
The CSS image() function is part of the CSS Images specification and is designed to describe an image value with more control than a plain url(). At its simplest, it lets CSS point to an external image resource, but it can also provide fallback behavior when that resource is unavailable or unsupported. The function is intended for properties that accept image values, such as background-image, border-image-source, list-style-image, and other image-capable CSS contexts.

A regular url() reference is straightforward: the browser requests the asset and uses it if it can. The image() function adds a layer of description around that source. It can identify an image as being appropriate for a particular writing direction, and it can include a solid color fallback to use if the image cannot be rendered. This makes it useful for interface graphics, decorative backgrounds, and assets that may need graceful degradation across different browsers or environments.
The most basic form looks similar to this:
background-image: image(url("pattern.avif"), #f3f3f3);
In this example, the browser attempts to use pattern.avif as the background image. If the image cannot be used, the color #f3f3f3 is available as a fallback image value. Unlike setting background-color separately, this fallback is part of the image value itself, which can matter when working with layered backgrounds or image-specific properties.
How it differs from common image syntax
url()references a single external resource.image()can wrap an image source with extra metadata and fallback behavior.- Direction keywords such as
ltrandrtlcan mark an image as suitable for left-to-right or right-to-left contexts. - Color fallback allows a CSS color to stand in when the image source is invalid or unavailable.
Directionality is one of the more specialized features. An icon, arrow, shadow, or decorative flourish may need to face a different way in an Arabic or Hebrew layout than it does in an English layout. With image(), an author can associate an image with ltr or rtl, allowing the browser to select the source that matches the element’s computed direction. This is cleaner than duplicating entire rulesets in some internationalized designs, although real-world support still affects whether it should be relied on directly.
The function also supports fallback to a color, which is treated as an image. This is useful when an external image format is not supported, an asset fails to load, or a user agent cannot process the supplied source. For example, a decorative card background can attempt to use a modern image while still rendering an acceptable flat color if the image value fails. That behavior is especially valuable for non-essential visuals, where the design should remain readable and stable even without the asset.
In practical modern CSS, image() is best treated as an enhancement rather than a universal replacement for url(). Browser support has historically been limited and uneven, so production styles should include a simpler declaration before the enhanced one. A safe pattern is to define a standard background-color and background-image: url(...) first, then add an image() declaration afterward for browsers that understand it. Unsupported browsers ignore the unfamiliar value and keep the earlier usable styling.
Syntax and Supported Arguments
The CSS image() function is written as an image value, which means it can be used anywhere CSS expects an image, such as background-image, border-image-source, or list-style-image. Its basic purpose is to describe one or more possible image sources, with optional fallback behavior when a source cannot be used.
The general syntax is:
image( [ <image-tags>? <image-src>? ,? <color>? ] )
In practical terms, the function can contain an image reference, an optional direction tag, and an optional fallback color. The image source is usually written with url(), although the CSS Images specification also allows other image-like values in some contexts. The color fallback is placed after the image source and is used when the image cannot be displayed.

image(url("photo.jpg")): defines a single image source.image(url("photo.jpg"), #eee): defines an image source with a color fallback.image(ltr url("arrow-left.svg")): defines an image intended for left-to-right writing contexts.image(rtl url("arrow-right.svg")): defines an image intended for right-to-left writing contexts.image(#f5f5f5): defines a solid color as the fallback image value.
The ltr and rtl keywords are directionality tags. They indicate that a particular image is suitable for a specific text direction. This is useful for icons, arrows, UI decorations, or illustrations that need to be mirrored or replaced in right-to-left layouts. These tags do not transform the image by themselves; they label the image so the user agent can choose the appropriate source when direction-aware selection is supported.
The fallback color is especially useful for resilient styling. If the browser cannot load the referenced file, does not support the image format, or cannot use the image value, the color can still be rendered. For example, a card background might use a decorative texture while falling back to a neutral color:
.card {
background-image: image(url("/assets/paper-texture.avif"), #faf7f0);
}
When using image(), keep the syntax conservative. Quote URLs when they contain special characters, always provide a sensible color fallback for decorative backgrounds, and avoid relying on image() as the only declaration if the image is essential to the interface. For broad compatibility, pair it with a widely supported fallback declaration before the enhanced version:

.hero {
background-image: url("/assets/hero.jpg");
background-image: image(url("/assets/hero.avif"), #1f2937);
}
In this pattern, browsers that do not understand image() keep the first background-image value, while browsers that support the function can use the enhanced declaration. This makes the syntax safe to experiment with in modern CSS without breaking older or less capable user agents.
Using Fallback Images and Colors
The image() function is designed to let CSS describe more than one possible image outcome in a single value. In practical terms, that means you can provide a primary image source and still give the browser something usable if that image cannot be displayed. A fallback can be another image, a solid color, or both depending on how you structure the value and what the browser supports.
A common pattern is to place an image URL inside image() and add a color fallback after it. If the referenced image is invalid, unsupported, or fails to load, the browser can use the color instead of leaving the painted area empty. This is especially useful for decorative backgrounds, icons, badges, and UI panels where a missing image should not make text unreadable or break the visual hierarchy.
For example, a background can be written with a preferred asset and a safe color fallback:
.hero {
background-image: image(url("hero.avif"), #1f2937);
background-color: #1f2937;
}
In this example, url("hero.avif") is the preferred image candidate, while #1f2937 gives the browser a solid color to paint if the image cannot be used. The separate background-color declaration is still valuable because it works in browsers that do not understand image() at all. If the entire background-image value is rejected, the element still has a predictable background color.

You can also use another image as the fallback when the design requires an actual graphic rather than a flat color. This is useful when serving a newer format first and a more widely supported format second:
.card {
background-image: image(url("pattern.avif"), url("pattern.png"), #ffffff);
background-color: #ffffff;
}
Here, the browser can attempt the AVIF version first, then fall back to the PNG version, and finally to white if neither image is available. This pattern keeps the declaration compact, but it should be used with care because support for image() itself is not universal. For broad compatibility, pair it with ordinary CSS declarations that older browsers can understand.
Safe fallback pattern
- Declare a basic
background-colorfirst for all browsers. - Declare a widely supported
background-image: url(...)fallback next if an image is required. - Add the enhanced
background-image: image(...)declaration last so supporting browsers can use it.
A progressive version might look like this:
.banner {
background-color: #0f172a;
background-image: url("banner.png");
background-image: image(url("banner.avif"), url("banner.png"), #0f172a);
}
This ordering matters because CSS uses the last valid declaration. Browsers without image() support ignore the final declaration and keep the earlier url("banner.png"). Browsers that support image() use the enhanced list and can select the first usable source or fall back to the color.
Color fallback is also helpful for accessibility. When a background image contains dark gradients or overlays behind light text, choose a fallback color that preserves contrast if the image fails. Treat the color as part of the design, not just an error state. A well-chosen fallback keeps buttons readable, cards distinct, and hero sections usable even when image loading is blocked by network conditions, browser limitations, or content security rules.

The image() function includes a directionality feature designed for images that need to change when the writing direction changes. This is useful for interfaces that support both left-to-right languages, such as English or French, and right-to-left languages, such as Arabic or Hebrew. Instead of writing separate selectors for each direction, authors can mark an image candidate as suitable for ltr or rtl directly inside the function.
The directional form uses ltr or rtl before the image source. In practical terms, this lets the browser select the image that matches the element’s computed direction. For example, an arrow, progress graphic, speech bubble tail, or decorative illustration may need to point in the opposite direction in an RTL layout. The syntax is compact:
background-image: image(
ltr url("arrow-right.svg"),
rtl url("arrow-left.svg")
);
In this example, an element in a left-to-right context uses arrow-right.svg, while an element in a right-to-left context uses arrow-left.svg. The direction is based on CSS directionality, usually coming from the document language, the dir attribute, or the CSS direction property. For instance, <html dir="rtl"> will generally cause descendants to compute as RTL unless overridden.

Where directional images are useful
- Navigation icons: next and previous arrows often need to reverse in RTL layouts.
- Decorative backgrounds: patterns or illustrations may have visual flow that should match reading direction.
- Callouts and speech bubbles: tails or pointers may need to move from one side to the other.
- Onboarding graphics: screenshots or diagrams that imply sequence can require mirrored assets.
A safer real-world pattern is to combine directional image candidates with a normal fallback declaration. Because support for image() is limited compared with long-established CSS image features such as url(), a plain background image should appear first. Browsers that do not understand image() keep the earlier value, while browsers that support it can use the direction-aware version.

background-image: url("arrow-right.svg");
background-image: image(

);
}
This pattern works well when the LTR version is an acceptable default. For a site with a primary RTL audience, the order can be adjusted so the fallback better matches the most common direction. You can also pair this with traditional direction selectors when you need stronger compatibility:
.next-step {
background-image: url("arrow-right.svg");
}
[dir="rtl"] .next-step {
background-image: url("arrow-left.svg");
}
.next-step {
background-image: image(
ltr url("arrow-right.svg"),
rtl url("arrow-left.svg")
);
}
Direction-aware images should be used for assets whose meaning or visual alignment changes with reading direction, not as a replacement for layout. If an icon can be mirrored with CSS transforms, that may be simpler and more widely supported. If the image itself contains text, create properly localized assets rather than relying on mirroring. For modern CSS, image(ltr ... , rtl ...) is best treated as a progressive enhancement: helpful where supported, harmless when guarded by ordinary url() fallbacks, and especially valuable in internationalized interfaces.
Practical Examples in CSS Backgrounds
The image() function is most commonly discussed as a value for image-accepting properties such as background-image, border-image-source, list-style-image, and similar CSS properties. In day-to-day interface work, backgrounds are the easiest place to apply it because the function can describe a preferred image source and a safe fallback in one declaration. This is useful for decorative UI artwork, localized illustrations, hero panels, and components that should still render acceptably when an asset fails.
Basic background fallback
A practical pattern is to provide a regular background color first, then use image() where supported. The color remains useful for older browsers, slow connections, missing image files, or cases where the image cannot be decoded. The image() function can also include a color fallback inside the function itself, giving the browser another value to use if the image source is invalid.
.promo-card {
background-color: #14315f;
background-image: image(url("/assets/promo.webp"), #14315f);
background-size: cover;
background-position: center;
color: white;
}
In this example, the card uses promo.webp as the intended visual background. If that source cannot be used, the declared color keeps text readable and preserves the overall design. For production CSS, keep contrast in mind: the fallback color should be chosen as carefully as the image, especially when text or controls sit above the background.
Multiple layers with gradients
image() can be combined with other background layers. A common approach is to place a gradient above the image to improve legibility. The gradient is not a fallback for the image; it is a separate layer that remains part of the design whether the image loads or not.

.hero {

image(url("/img/hero.avif"), #2b2f3a);
background-size: cover;
background-position: center;
}
This pattern is well suited to banners, article headers, and landing-page sections. If the image is unavailable, the fallback color from image() still sits under the gradient, producing a controlled visual result instead of an empty or transparent background.
Direction-aware decorative backgrounds
For interfaces that support left-to-right and right-to-left writing modes, image() can reference directional variants. This is helpful when an illustration contains arrows, people facing a direction, timelines, speech bubbles, or decorative shapes that should mirror the reading flow.
.onboarding-panel {
background-image: image(
ltr url("/img/onboarding-ltr.svg"),
rtl url("/img/onboarding-rtl.svg"),
#f4f7fb
);
background-repeat: no-repeat;
background-position: right bottom;
background-size: 320px auto;
}
When using direction-aware images, pair the CSS with correct document or component direction through dir="ltr", dir="rtl", or the CSS direction property where appropriate. Also test the fallback color alone, because users may see it in browsers without full support for directional image selection.

Safe use with progressive enhancement
Because support for image() is not as universal as long-established functions like url() and linear-gradient(), write declarations so unsupported browsers still receive a usable background. Put the broadly supported value first, then override it with image(). Browsers that do not understand the function ignore that declaration and keep the earlier one.
.feature-tile {
background-color: #eef3ff;
background-image: url("/img/feature.png");
background-image: image(url("/img/feature.avif"), #eef3ff);
background-repeat: no-repeat;
background-position: center;
background-size: cover;
}
This structure gives modern browsers the enhanced source while preserving a conventional url() path for others. For critical visuals, avoid relying on image() as the only declaration. Treat it as an enhancement layer: choose sensible colors, keep text readable, and verify the component with images disabled, failed URLs, and both document directions when localization is part of the design.
Browser Support and Progressive Enhancement
The image() function is defined in the CSS Images specification, but it is not yet a feature you can treat as universally available across production browsers. Support has historically been limited and inconsistent, especially compared with well-established image notations such as url(), gradients, image-set(), and ordinary fallback declarations. For that reason, image() is best handled as a progressive enhancement rather than the only way to supply a critical visual asset.
A safe pattern is to declare a broadly supported value first, then place the image() value later in the same rule. Browsers that do not understand image() will discard that declaration and keep the earlier one. Browsers that do support it can use the enhanced behavior, such as selecting an ltr or rtl source, trying mulle image options, or falling back to a solid color.
.hero {
background-image: url("/images/hero-default.jpg");
background-image: image(
url("/images/hero.avif"),
url("/images/hero.webp"),
url("/images/hero-default.jpg"),
#eceff3
);
}
For interface elements, keep essential meaning out of CSS background images altogether. If an image communicates content, use an HTML <img> element with proper alternate text or a <picture> element for format and source selection. The image() function is more appropriate for decorative backgrounds, icons that are duplicated by text, theme surfaces, and direction-aware visual polish.

- Declare a baseline first: use
url(), a gradient, or a background color before the enhancedimage()declaration. - Do not rely on it for required content: unsupported browsers may ignore the entire value.
- Test fallback behavior: simulate blocked image requests and unsupported syntax, not only successful image loads.
- Pair it with logical CSS: for left-to-right and right-to-left layouts, combine direction-aware images with properties such as
margin-inline,padding-inline, andinset-inline. - Use feature queries carefully:
@supportscan help, but test the exact value you plan to ship.
Feature queries are useful when the enhanced rule needs more than a single replacement declaration. For example, a component might use a simple background by default, then switch to an image() value only when the browser reports support for that syntax. This keeps the baseline compact while isolating the newer behavior.
.card-banner {
background-color: #dfe7f2;
background-image: url("/images/banner-basic.png");
}
@supports (background-image: image(url("/images/banner.avif"), #dfe7f2)) {
.card-banner {
background-image: image(
url("/images/banner.avif"),
url("/images/banner.png"),
#dfe7f2
);
}
}
Before shipping, check current compatibility data for the browsers and WebViews your audience actually uses. Enterprise environments, embedded browsers, older mobile devices, and in-app webviews can lag behind desktop releases. If the design remains readable and visually acceptable with the baseline declaration alone, then image() can be added safely as an enhancement without making the page fragile.
Frequently Asked Questions
Can I use CSS image() in production today?
You can use it, but only with feature checks or fallbacks because browser support is still limited compared with url(), image-set(), and gradients. A safe pattern is to declare a standard background-image first, then override it inside an @supports rule that tests image().

url() points to a single external resource, while image() can describe an image with extra fallback behavior. For example, image() can include a solid color fallback if the image cannot be rendered, and it can select direction-specific images for left-to-right or right-to-left layouts.
What happens if the image file inside image() fails to load?
If you provide a color fallback, the browser can render that color instead of leaving the image area empty. For backgrounds, this is useful when the image is decorative and you still need readable contrast behind text or interface elements.
Should I use image() or image-set() for responsive images?
Use image-set() when you need to provide different resolutions or formats, such as 1x and 2x assets or AVIF and PNG alternatives. Use image() when you need image fallback behavior, direction-aware assets, or a color fallback as part of the image value.
How do direction-aware images work with ltr and rtl?
The ltr and rtl options let you provide different image sources based on the document or element direction. This is useful for arrows, illustrations, chat bubbles, and interface graphics that need to mirror correctly in languages such as Arabic or Hebrew.
Bottom Line
The CSS image() function is designed to make image values more resilient by letting you define sources with optional fallback behavior, direction-aware variants, and even a final color fallback when an image cannot be used. While its syntax is promising, real-world support is still limited enough that it should not be treated as a universal replacement for url() yet.
Use image() cautiously in modern CSS: pair it with feature testing, keep a standard url() or solid color fallback nearby, and verify behavior across your target browsers. If support improves for your audience, it can become a cleaner way to express robust, localized, and failure-tolerant image choices directly in CSS.
