Question

I have the div, containig some html-formatted text like normal, <b>bold</b>, <i>italic</i>.
And I need to change font-size for all bold text only in that div.

So the question is how to do this in html/css, or maybe js?

Answer 1

div.foo b, div.foo strong {
  font-size: 1.2em
}

if you are using inline style like <i style="font-weight:bold"> case is more complicated.

Then you have to use jQuery+CSS

$('div.foo *[style=font-weight:bold]').addClass('myFontSize');

div.foo .myFontSize {
  font-size: 1.2em;
}

But please mind it’s not good practice.
