problem centering a block horizontally both IE and Firefox

[eonian]

Hi,

I try to center a block only horizontally using :

.conteneur {
height: 435px;
width: 689px;
margin: 0 auto;
text-align: left;

}

IE works fine but Firefox center the block not only horizontally but vertically too!

How to avoid that? I want my block to stay at the top vertically in firefox.

Thank you very much for your help.

eonian, welcome to WebmasterWorld.

Sounds like a body and padding issue. Set the body

body {
margin: 0;
padding: 0;
}

and add

.conteneur {
height: 435px;
width: 689px;
margin: 0 auto;
text-align: left;
padding: 0;
}

Remember, different browser clients have different defaults for their margins and padding in all elements. This is most obvious with <h> tags.
