I'm curious to find out how i can code this in css?

If i have a background image of wood and the wood texture changes across the page both horizontally and vertically.

i can't exactly have a single image (like a single horizontal line repeat). or a single vertical line repeat. If i take the line on the outside, it won't look like the vertical image or horizontal image inside.

such as this image for example, do you think it's possible to use this as a background image and how would i go about coding it or separating into multiple background images.
