You will need to be more specific. Strings do not have width or height. If you want to get the width or height of an element, you can but, it depends upon wether these are already defined or not and if defined, how they are defined, as to what method you use. In all cases the element must have been parsed by the browser before you query its dimensions. Here are some examples:

var element=document.getElementById('myID')

//For elements with attribute width & height defined:

alert(element.width);
alert(element.height);

//For elements with style width & height defined:

alert(element.style.width);
alert(element.style.height);

//For elements with no defined width or height

alert(element.offsetWidth);
alert(element.offsetHeight);

Hi

Thanks for the help.

<td> as the "align" and "valign" how do i do that in a <span>
or <div> ???

Span.height = 100
String(Text).height = 20

to align i do

(Span.height - String(Text).height) / 2 = 40

this is like the valign, but for this i need the String height.

I had the same question!
"element.offsetheight" doesn't work if height is set on "auto".
Need help, please!!!!

element.offsetheight won't work for anything. It's (praise to the all mighty camelBackNotation ):

element.offsetHeight

That should get you a number that represents the current layout height of the element in pixels, regardless of how it is styled.

Danke, man! Your my god!
I didn' know that upper and lower case is important in JS! I started learning it the day I logged in here the first time.
