title: Is Modernizr covering the prefix for css?
body: <p>Sorry for the silly question, but I am really beginner and I need your help.
  I added modernizr-2.8.3.min.js in my website.
  I visited the modernizr home page, but I don't understand how to download it.
  Then, I found this modernizr file in the html5 boilerplate.
  When I add this in my ,  is this helping me not to add vendor prefix?
  Or, if I do not do anything with modernizr, should I use some kind of 'prefix free' file?</p>
  
  <p>Thanks.</p>
