using font-size: 1px

why use this?

[12inch]

On serveral sites I see the code:

font-size: 1px;

What does this do?
I probably think it's a hack for something.

it could well be to effectively hide text from users in an effort to boost search engine rankings.

Not all uses are bad ;)

Some browsers will use font-size to override the height of elements..

So you cannot specify an elements height at less that the font size, (not handy if you want to make a 2px high graphic line or the like...)

so the solution is to set font-size to 1px.. that covers all eventualities
