Need help making color transparent and changing header text color

Hello,

I want to change my forum so that the color #C1B591 doesn't show and there is nothing but the posting and other page items showing. Additionally, I want to change the Advanced Search and my site description colors from their current white color to the color that the text "Board Index" is.

Lastly, I was told to put this into the border.css:

Code:

html, body { background-color: #c1b591;
    background-image: url("http://www.sitename.com/forum/styles/stylename/imageset/forum bkg.jpg");
    background-position: center;
    background-repeat: no-repeat;
    -webkit-background-size: cover;
    -moz-background-size: cover;
    -o-background-size: cover;
    background-size: cover;
    background-attachment: fixed;
    }

so that my background image will stay fixed. Pretty simple and it works perfectly, but I want to cut the background horizontally (halving it) so it will be a smaller file and hopefully quicker to load. If I do that, will the image still tile vertically as in html, or do I need to put repeat-y in the code?

I am very new to phpbb and don't have a clue when dealing with CSS. I fear I've already driven one person nuts with all the Q&A, but have a lot on my plate right now besides this, so things aren't sinking in at best.

My forum is at (removed)

Any help would be deeply appreciated. Thanks in advance!

My apologies. I thought this was a general help forum for boards. Will move on.
