Overview
Browser extension highlighting Bootstrap deprecated classes in websites
Highlight the Bootstrap classes that need to change when you migrate a website to another Bootstrap version. Open a website using Bootstrap, click the extension icon, and pick two versions: - Your site uses: the Bootstrap version of the website (preselected when it can be detected) - Migrating to: the version you want to migrate to (Bootstrap 3, 4, 5, or the Bootstrap 6 alpha) Click Highlight to outline in the page: - in red, the classes of your version that don't exist anymore in the target version - in yellow, the classes that still work in the target version, but are deprecated The popup tells you how many elements and classes have been found. Changing a version updates the highlighting right away, and Clear removes it. Examples: - Bootstrap 4 → 5: what needs to change to migrate to Bootstrap 5 - Bootstrap 5 → 5: the deprecated classes you can already replace before Bootstrap 6 - Bootstrap 5 → 6 alpha: a preview of a Bootstrap 6 migration Nothing is collected or sent anywhere.
