Bootstrap 3! My favourite front-end development framework has finally get its latest update. This new version follows the mobile-first approach and some of the components have been rewritten for better compatibility. Ever since the introduction of bootstraps, it was quickly adopted by many designers and developers.

I have made quite a few resource posts regarding bootstrap, the most famous posts are:

Now we have version 3. It's now mobile first, javascript plugins are rewritten and it's no longer support IE7 and Firefox.

What's New

Copy directly from Bootstrap Official blog :P

  • New design and an optional theme! With v3, we've gone flat. Don't call it a trend—it's all about customization, folks. Since we simplified the aesthetics though, we thought it'd help to have an optional theme. To use it, check out the Bootstrap theme example.
  • Mobile first and always responsive! Nearly everything has been redesigned and rebuilt to start from your handheld devices and scale up.
  • Brand new Customizer! Customizer has been redesigned, is now compiled in the browser instead of Heroku, has better dependency support, and even has built-in error handling. Better yet, we now save your customizations to an anonymous Gist for easy reuse, sharing, and modifications.
  • Better box model by default. Everything in Bootstrap gets box-sizing: border-box, making for easier sizing options and an enhanced grid system.
  • Super-powered grid system. With four tiers of grid classes—phones, tablets, desktops, and large desktops—you can do some super crazy awesome layouts.
  • Rewritten JavaScript plugins. All events are now namespaced, no-conflict stuff works way better, and more.
  • New Glyphicons icon font! While they were gone for a while, we've since restored the Glyphicons to the main repo. In 2.x, they were images, but now they're in font format and include 40 new glyphs.
  • Overhauled navbar. It's now always responsive and comes with some super handy and re-arrangable subcomponents.
  • Modals are way more responsive. We've overhauled the modal code to make it way more responsive on mobile devices. They now scroll the entire viewport instead of having a max-height.
  • Added some components! New to the mix are panels and list groups.
  • Removed some components! We've dropped the accordion (replaced with collapsible panels), submenus, typeahead, and a few more small items. (Worth celebrating as much as adding new ones.)
  • More consistent base and sizing classes. Buttons, tables, forms, alerts, and more have been updated to have more consistent classes for easier customizer and extensibility.
  • Docs have been blown up, yo. We've added a lot of new documentation, not only for our components, but for browser support (including gotchas and bugs), license FAQs, third party support (and workarounds), accessibility, and more.
  • Dropped Internet Explorer 7 and Firefox 3.6 support. For Internet Explorer 8, you'll need to include Respond.js for all the media queries to work correctly. You can read more about browser support in the docs.
