I wish to change the width of a pic to 100%. But don't want the height specified or affecting the width anyway and causing the image to distort.

What is the term to null/zero a height. I have been using /\* height: 68px; \*/ as a fix in the stylesheet for now. But there must be a better way?

Before

```
height: 68px;
width: 482px;

```

After
 /\* height: 68px; \*/
 width:100%
