Sorry Nobita, I want to add CSS like:

#comments {
font-size: 110%;
}

but in the posts

What kind of CSS have I to add?

Thanks, Nobita. It works.

I′ve forgotten, change to bigger font.

PD: Sorry for my bad English, I′m from Spain.

Thanks for the anwers.

It works, wPyogi.

Now I need change the font size in the posts, What CSS have I to add?

Ok, i′ve download the Simple Custom CSS pluguin.

What′s the next step?

I′ve installed Smart Youtube Pro, but the youtube embedded in the comments doesn′t work.

Thanks for the answer.
