Twitter’s Bootstrap 3 also delivers 6 button colors. Define your own button colors will a lot simpler as in Twitter’s Bootstrap 2. Cause TB3 drops support for IE7 the button css becomes more straight forward. Every button color still got 3 variants (default, active and disable). For the active state an background and border color are calculated based on the base color. The disable state use the base color and only adds a css-opacity.
TB3 not only drops IE7 support. Twitter’s Bootstrap 3 buttons don’t have a gradient. Also the text-shadow is removed.
I create a new Twitter Bootstrap Button Generator. Use this generator for Twitter’s Boostrap 3.x. Input a html color gives you the css code for your buttons. Add the css in your html after the Bootstrap’s CSS inclusion.
You got 2 choses of buttons. The default simple css and the more complex ‘old style’ css with added gradient. This new generator use Lessphp to generate the css code. Lessphp is a compiler for LESS written in PHP. See also: Twitter bootstrap buttons
