Re: Adjustment to the title font size
> Where should I look if I wanted to change the font size of the wiki page title and the font size at the the eidt area??
The title font is determined by the pagetitle class identifier. There is also an a.pagetitle (when the pagetitle is a link) which, being more specific, could override .pagetitle. Look for these in your stylesheet and change the font size.
By "eidt (edit) area," if you mean the text in the body of the wiki page, that's the wikitext div, so search for div.wikitext in your CSS file and change the font size as you like.
As a general rule, it's a great help to look at the source of the final HTML page (in your browser menu, go to "view source"). Copy a bit of text, such as the first few words in the part of the page you want to identify, and then find it in the source. Notice what div identifier encloses the words, and then find this in the theme's stylesheet file. Opera and Firefox also have page view options that will identify the page's structural elements.
