If you mean “Error Page V04,” the closest exact match is Colorlib Error 404 V4. Colorlib describes its September 2026 update as standalone HTML and CSS: it does not bundle Bootstrap, jQuery, plugins, or JavaScript, even though the page says it can be used in Bootstrap 4, 5, or 6 projects without changing its appearance.
What Error Page V04 is
Colorlib lists the template in its 404 Error category and includes a call-to-action button intended to take visitors back to the website’s home page. The page itself is dated March 19, 2021, while its template details separately list a September 2026 release/update. Those are different dates, not a single original publication date.

Despite “Bootstrap” in the title, the updated package is described as plain HTML and CSS. “Bootstrap-compatible” here means Colorlib says the page can be placed in a Bootstrap project and retain the same appearance; it does not mean the package supplies Bootstrap or depends on it.

#1 Best Overall
| Your situation | Reasonable approach | What to check |
|---|---|---|
| Your site already uses Bootstrap 4, 5, or 6 | Use the template as a standalone page or integrate its markup and styles into the existing project. | Keep the site’s existing framework assets and check for CSS conflicts with the template. |
| Your site does not use Bootstrap | Use the standalone HTML and CSS as described by Colorlib. | Confirm the page’s links, typography, and styling fit your site. |
| You need a deeply customized error page | Adapt the HTML and CSS to the site’s design system rather than adding framework files solely for this page. | Review the page at your target screen sizes and make sure its home-page button points to the correct destination. |
What the listed download and license mean
Colorlib lists the download at 309 KB and the license as CC BY 3.0 on its page. These are mutable listing details, so confirm the current package size and license terms on the live page before redistributing or putting the files into production. The listing says the update needs no JavaScript; it does not establish a performance benchmark or guarantee compatibility with every site’s CSS.

Bootstrap is a separate framework. Its official blog identifies version 5.3.8 as a release; that release information does not change Colorlib’s description of this template as standalone HTML and CSS. For current framework files and setup steps, use the official Bootstrap blog and its linked official resources. Bootstrap’s 3.4 getting-started documentation is version-specific legacy guidance, not a current setup guide. For other Bootstrap layouts, Start Bootstrap’s catalog offers general template browsing, but it is not evidence of another copy of this exact V4 page.
