A lightweight JavaScript plugin that detects outdated browsers and displays a styled notice advising users to upgrade. It is embedded in web pages via CSS, JS, and a small HTML snippet, with multi-language support.
Use cases
- detect old browsers visiting my website
- show upgrade notice to IE6/IE7 users
- warn users their browser doesn't support CSS3
- advise visitors to update their browser
- block modern site features on legacy browsers gracefully
When to choose
- your site relies on modern CSS3/HTML5 features and you want to inform legacy-browser users
- you need a simple, dependency-free (or jQuery-compatible) drop-in script
- you want multilingual upgrade notices
When to avoid
- you need feature detection rather than browser-version detection (use Modernizr)
- your project no longer supports legacy browsers at all
- you want active development or modern ES module integration
