 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 built my layout using Tabula Rasa, and the theme wizard. Googled my way to adding a pinch of CSS code (while being utterly code illiterate) so my icons right justify and there's an added border on the left. I really like what I was able to achieve.

BUT I'm looking for some help in tweaking the look of comments on the page i.e. here. They look too cluttered to me.

What really I want to do is find a way to let the date/time of the comment and the user details (IP Address) be in a far smaller font, or be outlined in a box, so that they don't detract from whatever the actual comment is.

Can anyone help? And how complicated would this be to code so that only the comment boxes changed?

So, I have a custom LJ lay out. I copyed the CSS from it to here, but it is off. I don't know enough to fix it, can anyone tell me what to do?

Hello, this is just an introductory post so to fiddle with the layout of this place. Please feel free to join and post at your leisure. :)
