background

[shadowcast]

I like to change my site back ground to image i use.
But before i do anything, i like to ask how to go about it.

In theory wise i will put the background into the image folder,But my question is how can i link it to use that image?

textarea{ margin: auto; display: block; width: 95%; }
input:focus, select:focus, textarea:focus{ background: #f5f5f5; }
