Change text size

[Jeff Ledger]

How hard is to do this that nobody wants to help me?

It's not that hard but it tooks a lot of times and in this case, I prefer work directly on the style than putting some css here.

To make it looks exactly like what you wanted, edit css only is not enough, you will need to hard-edit the template which refered to the block.

But it's possible, I did it on my theme once too. Just always have a backup template to compare, try one by one all the detail and there's you go.
