The textarea remains the real editing surface; the highlighted layer is display-only. The main challenges are keeping those layers visually aligned and preventing untrusted SVG markup from becoming active in the page.
Use a textarea as the source editor
A native <textarea> already handles multiline text entry, selection, keyboard input, and exposes its content through value. Keep that value as the canonical source instead of trying to turn a rendered syntax-colored DOM into the editor. This preserves familiar browser editing behavior and avoids implementing text editing yourself. See MDN’s textarea reference.

Give the control an accessible label, such as “SVG source.” Keep focus and keyboard input on the textarea even when the highlighted display is visible. Its selectionStart and selectionEnd properties provide selection offsets if editor logic needs to preserve or inspect the caret and selection. See MDN’s selectionStart documentation.
Render syntax colors in a synchronized layer
A practical no-library design puts a highlighted <pre> beneath a transparent textarea. The textarea receives typing and pointer events; the lower layer displays the source with token spans styled in different colors. This pattern is described in Helge Sverre’s overlay tutorial.

For the text to appear in the same place in both layers, match their font family, font size, line height, padding, whitespace handling, tab sizing, wrapping, and overflow behavior. Copy the textarea’s horizontal and vertical scroll offsets to the highlighted layer when it scrolls. An extra newline or other end-of-input handling may be needed so the final line remains visible. These are layout requirements of the overlay approach, not guarantees supplied automatically by the browser.
Keep the textarea caret and selection perceptible against the display layer, and ensure the overlay does not intercept input. Check the result at different zoom levels, with long lines, tabs, wrapped text, and a trailing newline. Misaligned line heights or scroll positions make the displayed colors appear to belong to different text than the source being edited.

Tokenize source without turning it into executable HTML
When producing highlighted spans, treat every character from the textarea as untrusted text. Escape source text before building HTML, or create elements and append text nodes so the source is never interpreted as markup. Then add spans only for the tokens your highlighter identifies.

Parse SVG and update the preview with a security boundary
To check whether source is well-formed XML, parse it with DOMParser.parseFromString(source, "image/svg+xml"). The parser returns a separate in-memory document; malformed XML produces a parsererror node that your editor can detect and report instead of presenting the source as a valid preview. MDN documents the SVG/XML mode and parser errors in its DOMParser reference.
A successful parse is not a safety check. Parsed content may be initially separate from the active page, but scripts or event handlers can run when content is inserted into the visible document. Treat any move from user-authored text to rendered markup as a security boundary. Define which SVG elements, attributes, links, and external resources your editor permits, sanitize according to that policy, and use an appropriately isolated preview context with a restrictive Content Security Policy where appropriate. The right allowlist depends on the editor’s intended features.

For a simple playground, separate the jobs: validate XML structure, apply the chosen feature policy, and only then update the preview through a controlled and isolated rendering path. Do not use an unsanitized markup string as a shortcut into the host page.
Consider the CSS Custom Highlight API for text-range styling
The CSS Custom Highlight API styles text ranges without changing the document’s DOM structure, and MDN notes that it can be used for text-editing applications. It is another no-library option, but its browser availability needs checking against your actual target browsers: MDN reports support in the latest devices since June 2025 while warning that older devices may not support it. Consult the current CSS Custom Highlight API documentation and its compatibility information before relying on it.

| Approach | What it offers | Main implementation concern |
|---|---|---|
| Textarea with highlighted overlay | Native textarea editing with a separate colored rendering layer. | Keep typography, whitespace, wrapping, scrolling, caret, and selection presentation aligned. |
| CSS Custom Highlight API | Styles ranges without restructuring the text’s DOM. | Check browser support and manage token-to-range mapping. |
Neither approach has a performance advantage established by the cited sources. Compare them against your browser coverage, selection and caret fidelity, input-method editor behavior, token-to-range complexity, document size, and accessibility needs; measure performance with the documents and devices you expect to support.
