Can't resize with css font-size

[MiroStW]

To change the size of an icon I normally use font-size. This works with the regular glyphicons in bootstrap, however it does not work with icon-large icons.

Is there another way to do this?

Thanks Miro

I am REALLY late to the party but if anyone is looking for a solution then one way of resizing an icon is like this:

.icon-large{
    transform: scale(1.5);
}

Keep in mind that it won't look very pretty.
