My site is made using the Writer template. I want to tweak some things at the top of the page (see HERE), but I'm pretty clueless as to how this stuff is put together. I don't know what to ask about in the Help section.

Basically I want to decrease the height of Areas 1 and 5, so that these things show up smaller on every page of the site.

I need a little guidance in getting started. (Later, I might want to increase the width of the whole site, which I think will require me to know a lot about this stuff.)

BTW, the wide text area in the example came about by my width experiments on another page HERE.
