How do you create a web page background?
The background of your web site is an important consideration. We generally recommend a solid light color. This makes your text easier to read and makes your images more vibrant.
A background is created with a simple CSS property. For a solid color it is background-color. For an image it is background-image. If you use an image you can also determine whether the image repeats, where it is positioned, and whether it is attached to the screen or not.
The tiled or wallpaper looking background is not as popular as it was in the early days of the web. Generally the overall look is kind of ugly. Some interesting looks can be achieved with gradients or quasi framing effects.
Since the background is what everything else lays against, you should determine with your web designer your preferences for a background as early as possible in the process.
