Basic Bootstrap Tempate

<!DOCTYPE html>
    <title>Bootstrap Starter Template</title>
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.0.2/css/bootstrap.min.css">
    <h2>Hello, world!</h2>
    <script src="https://code.jquery.com/jquery.js"></script>
    <script src="//netdna.bootstrapcdn.com/bootstrap/3.0.2/js/bootstrap.min.js"></script>

Visualize CSS

Let's add some CSS so we can see our grid for now.

.row div {
  padding-top: 10px;
  padding-bottom: 10px;
  color: #FCF4DC;
  background-color: #475B62;
  border: 1px solid #0A2933;

Paste this into JSBin's CSS tab

The mighty grid

  • Get a grid by adding classes
    <div class="row">
      <div class="col-md-4">First</div>
      <div class="col-md-8">Second</div>
  • col-breakpoint-count
  • By default should add to 12
  • Breakpoints
    xs: <768px, sm: ≥768px, md: ≥992px, lg: ≥1200px

The mighty grid

  • Use a container class to center on page
    <div class="container">
      <div class="row">
        <div class="col-xs-12 col-sm-4 col-md-8">First</div>
        <div class="col-xs-12 col-sm-8 col-md-4">Second</div>

Responsive Utilities

  • Easily show/hide content from devices

Responsive Columns

in action

    <div class="container">
      <div class="row">
        <div class="col-xs-12 col-sm-4 col-md-2">First</div>
        <div class="col-xs-12 col-sm-8 col-md-8">Second</div>
        <div class="col-xs-12 hidden-sm col-md-2">Third</div>
  • The third column has super powers
  • hide a column at any breakpoint

Other column options

  • Reset if columns don't clear
  • Offset if you want to lay them out of place
  • Nested if you want one to go inside another
  • Overridden if you want to change the order

LESS control

Excellent default CSS styles

  • Everything reset to Helvetica Neue
  • LESS variables for tweaking
  • Custom build if you don't like

Awesome Utility Classes

  • Controversial
  • Good enough for them!

Is it for me?

Unless you're an alien or Chuck Norris...yes


  • I can do the same thing quicker with Sass, Less, Compass, Git, Grunt
  • Is it road tested by millions of users?
  • Fluid, responsive components
  • Hey there Chuck, loved your work in The Octagon


  • I hate using so many classes
  • Got you champ...try Susy instead
