Modernizr is a small JavaScript library that detects the availability of native implementations for next-generation web technologies, i.e. features that stem from the HTML5 and CSS3 specifications.
This gem is a (hopefully temporary) fork of modernizr-rails, due to working around an error thrown in IE7. See issue 3 for status.
Add the following to your GemFile:
gem 'modernizr-examtime', :git => 'git@github.com:ExamTime/modernizr-examtime.git'
Then add the following to your application.js manifest:
//= require modernizr
Don't forget to run bundle update after upgrading to the latest gem version to ensure it's used by your Rails app.
