Locopon,

Thank you very much for your answer and trying to help me. Unfortunately, I should not phrase correctly my question, because I do not understand what you said...

I will try to re-phrase my question:
In my website, I have some HTML module. Inside this HTML module, I put some text (without any formatting, just typing some text). I would like this text to be bigger everywhere (I know that I can modify the size of the text inside the fckeditor, but I prefer modifying the global size of the text somewhere else, instead of editing all modules to have the size of the text bigger). You follow me ??

Question: which file should I modify to define the normal text as font-size: 18px (this is an example) ???
