## W3 CSS Containers
W3.css provides a container class which adds 16 pixels worth of left and right padding to any html element, and 0.01em of
top and bottom padding.
This makes it ideal for html containing elements such as ```<header>, <div>, <footer>, <section>```etc. But can also be used with great effect on elements like ```<img> and <p>.```

### Simple example
```html
<header class="w3-container">
  <h1>Header With W3 Container</h1>
</header>
```
```html
<header>
  <h1>Header Without W3 Container</h1>
</header>
```
Would produce the following result.
