{{_i}}About mixins{{/i}}

{{_i}}Basic mixins{{/i}}

{{_i}}A basic mixin is essentially an include or a partial for a snippet of CSS. They're written just like a CSS class and can be called anywhere.{{/i}}

.element {
  .clearfix();
}

{{_i}}Parametric mixins{{/i}}

{{_i}}A parametric mixin is just like a basic mixin, but it also accepts parameters (hence the name) with optional default values.{{/i}}

.element {
  .border-radius(4px);
}

{{_i}}Easily add your own{{/i}}

{{_i}}Nearly all of Bootstrap's mixins are stored in mixins.less, a wonderful utility .less file that enables you to use a mixin in any of the .less files in the toolkit.{{/i}}

{{_i}}So, go ahead and use the existing ones or feel free to add your own as you need.{{/i}}

{{_i}}Note: If you're submitting a pull request to GitHub with modified CSS, you must recompile the CSS via any of these methods.{{/i}}

{{_i}}Tools for compiling{{/i}}

{{_i}}Node with makefile{{/i}}

{{_i}}Install the LESS command line compiler with npm by running the following command:{{/i}}

$ npm install less

{{_i}}Once installed just run make from the root of your bootstrap directory and you're all set.{{/i}}

{{_i}}Additionally, if you have watchr installed, you may run make watch to have bootstrap automatically rebuilt every time you edit a file in the bootstrap lib (this isn't required, just a convenience method).{{/i}}

{{_i}}Command line{{/i}}

{{_i}}Install the LESS command line tool via Node and run the following command:{{/i}}

$ lessc ./lib/bootstrap.less > bootstrap.css

{{_i}}Be sure to include --compress in that command if you're trying to save some bytes!{{/i}}

{{_i}}Javascript{{/i}}

{{_i}}Download the latest Less.js and include the path to it (and Bootstrap) in the <head>.{{/i}}

<link rel="stylesheet/less" href="/path/to/bootstrap.less">
<script src="/path/to/less.js"></script>

{{_i}}To recompile the .less files, just save them and reload your page. Less.js compiles them and stores them in local storage.{{/i}}

{{_i}}Unofficial Mac app{{/i}}

{{_i}}The unofficial Mac app watches directories of .less files and compiles the code to local files after every save of a watched .less file.{{/i}}

{{_i}}If you like, you can toggle preferences in the app for automatic minifying and which directory the compiled files end up in.{{/i}}
