## Description
|
|
<section id='description'>
|
|
Another positioning technique is to center a block element horizontally. One way to do this is to set its <code>margin</code> to a value of auto.
|
|
This method works for images, too. Images are inline elements by default, but can be changed to block elements when you set the <code>display</code> property to block.
