The likely match for “Error Page V04” is Colorlib Error 404 V4. Colorlib describes its September 2026 update as a standalone HTML-and-CSS page: it does not require Bootstrap, JavaScript, jQuery, or plugins. You can use it on a non-Bootstrap site or add it to a Bootstrap project; the page says it keeps the same appearance in Bootstrap 4, 5, or 6 projects.
What is Colorlib Error 404 V4?
It is a 404 error-page template: a page visitors may reach when a requested address cannot be found. The design includes a call-to-action button intended to take visitors back to the site’s home page. Colorlib lists it in its 404 Error category and says it can be used on any website, whether or not that site uses Bootstrap.
The page’s date and update details refer to different things. It lists Rok Krivec as author and March 19, 2021 as the page date, while its template details say “Released: September 2026” and describe a September 2026 update. Treat the latter as the stated update/release information, not as the original page date.
Does it require Bootstrap?
No. Colorlib says the updated template is made with plain HTML and CSS and does not include Bootstrap files. It also says the page needs no JavaScript, jQuery, or plugins. “Bootstrap error page” therefore describes its intended compatibility, not a requirement to install Bootstrap.
#1 Best Overall
Colorlib claims the template can be placed into Bootstrap 4, 5, or 6 projects with the same appearance. That is the publisher’s compatibility statement; it does not establish independent testing across those versions. Bootstrap’s official blog identifies v5.3.8 as a release, but framework release information does not mean this template bundles Bootstrap. See the Bootstrap official blog for framework updates.
Choose an integration approach
| Situation | Practical approach |
|---|---|
| Your site does not use Bootstrap | Use the template as a standalone HTML-and-CSS page, adapting its links and styling to your site. |
| Your site already uses Bootstrap | Integrate the page into the existing project rather than adding framework files solely for this template. Check that its styles fit your site’s own CSS and layout. |
| You need substantial design-system changes | Inspect and customize the HTML and CSS before deployment. The source does not provide comparative testing of customization effort or performance. |
Bootstrap’s versioned 3.4 getting-started documentation covers compiled CSS and JavaScript assets, source files, examples, and Bootlint, but it is legacy documentation rather than current setup guidance. Consult it only when working specifically with that older version: Bootstrap 3.4 getting started.
Download size and license
Colorlib lists the download at 309 KB and the license as CC BY 3.0. These are mutable details on the publisher’s page, so check the live listing and the downloaded package before using or redistributing the template. Confirm the license terms and any attribution requirements for your intended use rather than assuming the listing alone settles them.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
What to check before publishing
- Open the Colorlib Error 404 V4 listing and confirm the current download and license details.
- Inspect the downloaded files to verify the package contents and identify the HTML and CSS you need.
- Update the home-page destination and any other links so they point to the right pages on your site.
- Test the 404 page on the target site, including its layout and styles alongside the site’s existing CSS and, if applicable, Bootstrap version.
- Check the final page in a browser and verify that its return-home button works before deploying.
How it compares with other template catalogs
Start Bootstrap’s catalog offers free and paid Bootstrap layouts, but its catalog is general marketplace context, not evidence that it includes this specific V4 page. Browse its template catalog if you want to explore other layouts; compare each option’s actual framework requirements and license rather than assuming they match Colorlib’s template.
