Page Background. I really need help. Thank You.

Hello,

In many sites I see a background which is composed by paralel thin lines
which have something like 30º or 45º angle with the horizontal.

I tryied to create a gif but when I use in as a page background image
the lines never look continuos. Can somebody help me out with this?

I need to have the design ready today and I have no idea what else to
do.

Thanks,
Miguel

Make a quite small image - something like 6x6 pixels - with a single, thin
line at a 45 degree angle going directly from one corner diagonally to the
opposite corner and then use this image as a background on the page or in a
table cell and let it repeat.
