NEED HELP WITH: border codes, title capitalization, & header + layout width

[refno619012]

 Hi all!

I just joined DW a few days ago, and I've managed to get my layout basically to how I want it to look.  There are a few things I need help with, though:

• I'd like to add a tiny one-pixel-wide border around my header, entries, modules, and entry comments, but am not sure what code to use.
• I'd also like to put the titles of my entries and the headers of my modules in lower-case letters. I tried looking through the customization options, but there doesn't seem to be one for capitalization.  :\
• And lastly!  I've noticed that the width of my header and layout are dynamic and change as I shrink the browser window.  Is there any way to change both so that they are static?

I'd appreciate any help that anyone could offer me.  :)
