html - Default CSS values for a fieldset <legend>

Question

I'm trying to use a <legend> as a title inside a <fieldset>.

In browsers other than IE, the <legend> is positioned on the top border of the <fieldset>, with the text perfectly centered on the line.

I'm trying to reset it's position so that it sits just like any other element. i.e. an <h3>.

Here's the CSS I have so far.

fieldset legend {
    margin: 0;
    padding: 0;
    position: static;
    border: 0;
    top: auto; left: auto;
    float: none;
    display: block;
    font-size: 14px;
    line-height: 18px;
}

But the legend is still perfectly centered on the line.

Yes, I can add a margin/padding/top coordinate but I want to know if the browser has any default values for the element that trigger this layout. I want to then, override these values.

Tested in Firefox (3.6.10), Chrome (6.0.472.63), Safari (5.0.2)

Update I'll leave this question open for another week just in case someone HAS been able to style <legend> elements. If no solutions are found I'll accept @jnpcl's answer.

Answer 1

This is enough :

 form legend{
    float: left;
    width: 100%;
 }
