I am creating some pages with a blue vertical strip on the left side while the rest of the page is white. Just like e.g. the search result pages of hotbot.
The background image that one uses to make such a page is usually only a couple of pixels high but on several different sites it is between 1280 and 3000 pixels
wide. Why is this?
And if I want to create a blue vertical strip on the right side of the page, what are then more or less the proportions? (I have seen one page with an image size:
width 720 pixels and height 12 pixels)
