Using line-height

You can also use line-height to center vertically a single line of text inside a container :

CSS

div {
    height: 200px;
    line-height: 200px;
}

That’s quite ugly, but can be useful inside an <input /> element. The line-height property works only when the text to be centered spans a single line. If the text wraps into multiple lines, the resulting output won’t be centered.
