I would like to change/customize one aspect in a wordpress theme (which cannot be change in the themes options) using the style.css or any other file in the editor. I would like to replace the 950px X 300px banner image (the image with various mobile devices and computer monitor) with a widget (WOWSlider) and adjust the size of that widget to 950px X 300px.
Extra important info:
(I do not have html/php experience) I have already successfully changed most of the colors on the theme manually through the style.css file to match my logo. I search the style.css file for “950px” and I found the region of interest( I believe):
margin: 20px 0;
background: url("images/sback.png") repeat scroll 0 0 #2E3036;
padding: 20px 0 0;
margin: 0 auto;
