Consider the following example: (live demo here)
HTML:
<a><img src="http://img.brothersoft.com/icon/softimage/s/smiley.s_challenge-131939.jpeg" /></a>
CSS:
a {
display: block;
background: #000;
line-height: 40px;
}
img {
vertical-align: middle;
}
The output is:
Why the image is not vertically centered ?
How could I fix that so it will work in all major browsers ?
Please don't assume any image size (like 32x32 in this case), because in the real case the image size is unknown.
