A trend of the 90’s which has persisted in the dark depths of the internet are background textures. These are images which when tiled next to each other produce a (hopefully) seamless pattern. Popular backgrounds in the early days were stars, logos, sand, crinkled paper and clouds.
Background textures should be used sparingly, if at all. They should definitely not have text written over the top of them.
If a texture is part of your brand, use it on the non-text areas of your website.
