Modernizr - Frontend development done right

Modernizr tests which native CSS3 and HTML5 features are available in each browser and makes the results available to you in two ways: as properties on a global Modernizr object, and as classes on the <html> element. This information allows you to progressively enhance your pages with a granular level of control over the experience.

This Drupal module provides deep integration with the Modernizr JS library, allowing other modules or themes to register tests, load additional assets as needed, and even create new copies of the Modernizr library when a website's requirements change. Read more below.


  • Download a Modernizr custom build
  • Copy modernizr-X.Y.min.js to sites/all/modules/modernizr/js/modernizr.min.js
  • If you have the Libraries API module installed, use the path sites/all/libraries/modernizr/modernizr.min.js instead.
  • Enable the module

If you use Drush, the module will automatically download a development version for you when you enable the module.

What is Modernizr?


Why use Modernizr?

Taking advantage of cool new web technologies is great fun until you have to support browsers that lag behind. Modernizr makes it easy for you to write conditional JavaScript and CSS to handle each situation, whether a browser supports a feature or not. It’s perfect for doing progressive enhancement easily.

How it works

Modernizr runs quickly on page load to detect features; it then creates a JavaScript object with the results, and adds classes to the <html> element for you to key your CSS on. Modernizr supports dozens of tests, and optionally includes yepnope.js for conditional loading of external .js and .css resources.
