## Description
|
|
<section id='description'>
|
|
The simplest way to make your images appear "retina" (and optimize them for retina displays) is to define their <code>width</code> and <code>height</code> values as only half of what the original file is.
|
|
Here is an example of an image that is only using half of the original height and width:
|
|
<blockquote><style><br> img { height: 250px; width: 250px; }<br></style><br><img src="coolPic500x500" alt="A most excellent picture"></blockquote>
|

|
|
## Instructions
|
|
<section id='instructions'>
|
|
Set the <code>width</code> and <code>height</code> of the <code>img</code> tag to half of their original values. In this case, both the original <code>height</code> and the original <code>width</code> are 200px.
