What does it mean background-position:0px 100px;?

What does it mean actually
background-repeat:repeat-x;
background-position:0px 100px;

if I use this in body?

It means
-don't "tile" or repeat the background once the full image has been displayed
-place the background on the left and 100px from the top.

I thought repeat-x meant to repeat the image across the x-axis (left to right) and repeat-y meant to repeat along the y-axis (top to bottom) ?

[KDLA]

You're right. I misread the post.

[toplisek]

so,when 100 % is width it will bring width all over display whatever size and resolution?
Should be such menu bg position ABSOLUTE as it is within DIV with fixed width...
