HTML background is the HTML attribute used to place pictures in the background of HTML elements.
When we think of an HTML background, we generally have only two options: a solid background color or a background image. The backgrounds of both the background color and image grow or shrink dynamically with the growth and shrinkage of the HTML element they are contained in.
