Modernizr: the feature detection library for HTML5/CSS3
Modernizr helps you detect HTML5 and CSS3 features in users’ browsers so you can build websites that work smoothly across different devices and browsers.
Modernizr is a handy tool for web developers who want to make sure their sites work for everyone, no matter what browser or device someone is using. It runs quick tests on a visitor’s browser to see which HTML5 and CSS3 features are supported, giving you the info you need to adjust your site’s experience on the fly.
With Modernizr, you can serve up different styles or scripts depending on what the user’s browser can handle, helping you avoid broken layouts or missing features. It’s especially useful if you want your website to look great and function well for all your visitors, even if they’re using older browsers. Whether you’re building a simple site or something complex, Modernizr makes feature detection simple and reliable.
