Line-height affects images?

http://jsfiddle.net/xJmZt/

As you can see in the above example , there is extra height of about 6px on the div.

That ex开发者_开发百科tra height is gone if line-height is changed to ~1px (link).

So line-height affects images too ?

Images by default are defined as inline elements so they follow text rules, you can either set the container height to match the images', or give the image display: block or vertical-align: bottom.
