Mysterious "margin" below an image

Consider the following HTML & CSS:

<div><img src='' /></div>

img {
background-color: red;
div {
border: 1px solid black;

This will leave a margin of about 5px between the lower edge of the image and the containing div, although there are no paddings or margins set, and there's no whitespace. The reason is, the image will vertically align baseline, and the space below the image is just kept for descenders (the part of letters below the baseline).

Fix it by either giving the image a vertical-align: middle or display: block, which in most cases should be what you want.

Once an application no longer requires constant development, it needs periodic maintenance for stable and secure operation. makandra offers monthly maintenance contracts that let you focus on your business while we make sure the lights stay on.
