[RESOLVED] Change Font Size

**xianxianxian200** · 12-05-2011 03:53 PM

I have a font tag I am trying to change the size of. The tag is simply this:

[tt]Text that's too big[/tt]

I can't change the tag so I am using the following code to try and modify it but to no avail:

Code:

<script type="text/javascript">
//<!--

var title = document.getElementsByTagName('font');
if (title.size == '5') {
    title.style.fontsize = '12pt';
}
//-->
</script>

getelementsbytagname returns a collection (kind of like an array) so it is best to loop through it, even if you know it is only one element.

also, when converting css tags that have a hyphen into DOM commands (I have no idea if I have the terminology right here, but bear with me) they generally become camel case, so font-size becomes fontSize. try this:

Code:

<!html>
<head>
</head>
<body>
<font size="5">Text that's too big</font>
<input type="button"  value="click me!" onclick="changeSize()">
<script type="text/javascript">

function changeSize(){
var title = document.getElementsByTagName('font');
for(i=0;i<title.length;i++){
if (title[i].size == '5') {
    title[i].style.fontSize = '12pt';
    }
}
}
</script>
</body>
</html>

What's a tag?

Thank you for the new code. But I need it to automatically resize the font onpageload instead of via a button.

And a tag is a basic format tag in HTML. You can add in in a variety of variables and values (just to include a few):

 

For more information I would suggest visiting W3Schools and going through their HTML tutorial section. I hope this helped.

Nevermind I got it to work window.onload = functionname;

Can a mod or admin please mark this as done. It won't let me edit my posts even though it says I may down at the bottom.
