 1. Wrap everything in a div element with the `container` class.
 
-'''html
+```html
 <div class="container"></div>
-'''
+```
 
 2. To create rows add div elements with the `row` and `clearfix` classes.
 
-'''html
+```html
 <div class="container">
     <div class="row clearfix"></div>
 </div>
-'''
+```
 
 2. To create columns add div elements with the `column` class. Then add a class
 to describe the width of the column with respect to the container. The possible
 widths are:
 
-* full: 100% width
+CSS class name  | width percentage
-* two-thirds: 66.7% width
+--------------- | ----------------
-* half: 50% width
+full            | 100%
-* third: 33.3% width
+two-thirds      | 66.7%
-* fourth: 25% width
+half            | 50%
-* three-fourths: 75% width
+third           | 33.3%
+fourth          | 25%
+three-fourths   | 75%
 
 These are purely for convienence. A more precise width can be specified in the
 CSS if desired with the `width` attribute.
 
-'''html
+```html
 <div class="container">
     <div class="row clearfix">
         <div class="column full"></div>
     </div>
 </div>
-'''
+```
 
 3. Columns stack up right to left. To force a column out of order all the way to
 the right use the `flow-opposite` class on the column.
 
-'''html
+```html
 <div class="container">
     <div class="row clearfix">
         <div class="column half"></div>
         <div class="column half flow-opposite"></div>
     </div>
 </div>
-'''
+```
 
 4. To hide an element on mobile phones add the class `hide-mobile`. To hide on
 desktop, use `hide-desktop` instead.
 
-'''html
+```html
 <div class="container">
     <div class="row clearfix">
         <div class="column half hide-mobile"></div>
         <div class="column half hide-desktop"></div>
     </div>
 </div>
-'''
+```
 
 5. Another note: I use [box-sizing (as suggested by Paul
 Irish)](http://www.paulirish.com/2012/box-sizing-border-box-ftw/), which I think
