maestro: Try this:

<BLOCKQUOTE><FONT face="Verdana, Arial">code:</font><HR><pre>
function changeFontsize(increment) {

var getElement = document.getElementsByTagName("p");

for (var i=0; i<getElement.length; i++) {
var eachElement = getElement[i];

if (document.defaultView) {
var currentFontSize = document.defaultView.getComputedStyle(eachElement, null).getPropertyValue(fontSize);
}
else if (eachElement.currentStyle) {
var currentFontSize = eachElement.currentStyle.fontSize;
}

var currFontSize = parseInt(currentFontSize, 10);

var fontIncrease = parseInt(increment, 10);

if (increment>0

hi emperor, thanks for the help. i know the script for changing the font size but what if the text that i want the font size changed, is in an iframe? can i use the 'target' within the <a> tag?

what i mean is that the button resides on the main html but i want the user to click this button and it changes the font size of the text IN the iframe...

maestro: Well I hate frames and try to avoid them where I can - I'd try changing 'document' in the above code to something like parent.FRAMENAME I believe that should work (if not someone will jump in with the correct solution ).

Emperor is right, just change document.getElementsByTagName("p") to something like parent.frames["frameName"].document.getElementsByTagName("p") and everything will be fine.

BTW File that is loaded in IFRAME must be on the same domain as the calling page, or you'll get "access denied" error message (web browsers don't allow changing pages that are not on the same domain).
