• On all browsers:

  • Normalize.css to make all the browsers have the same CSS base.
  • PrefixFree.js to avoid writing vendor prefixes.
  • H5F.js to enable HTML5 forms featues on all browsers (automatic installation by BC).
  • html5media.js to provide cross-browser support for <audio> and <video> tags and encodings.

• On old IE versions:

  • HTML5shim.js to make them understand HTML5 tags.
  • IE9.js + ie7-squish to make them understand most CSS selectors and properties without hacks. (BC enables PNG fix)
  • PIE.js to make them understand CSS3 decorations without filters (automatic use by BC).
  • FlashCanvas to make them display <canvas> tags.

• No dependencies - you may use jQuery or any other lib.

• Lightweight (~12kb gzipped for modern browsers, ~27kb for IE9, ~46kb gzipped for IE<9)
• Compatible with IE5+, FF2+ and all modern browsers.
