is there a way in javascript/css that i can change text size of all the labels, headings, paragraphs etc on a single click and without explicitly getting element's id and then changing its font size.
what i am doing right now is that i get element's id through javascript and change its font size explicitly. To get a clear picture of what i am doing check this link or check the following code
<script type="text/javascript">
function changemysize(myvalue) {
var div = document.getElementById("mymain");
div.style.fontSize = myvalue + "px";
}
</script>
HTML code
Choose a text size:
<font size="2"><a href="javascript:void(0);" onclick="changemysize(16);">A</a></font>
<font size="4"><a href="javascript:void(0);" onclick="changemysize(20);">A</a></font>
<font size="5"><a href="javascript:void(0);" onclick="changemysize(25);">A</a></font>
<div id="mymain">
Only this text gets affected
</div>
