Why Does Body Background Styling Affect the Entire Screen?

Body Background Styling: Impact on the Entire Screen

In web development, when styling the background of the

element, an unexpected effect may arise: the styling affects the entire screen rather than just the element itself. This phenomenon can be puzzling and requires an understanding of the cascading style sheet (CSS) rules governing the behavior.

According to the CSS specification, "The background of the root element becomes the background of the canvas and covers the entire canvas." This means that when you set a background color or other styling properties for the

element, which is considered the root element, the styling applies to the entire webpage area within the browser's viewport, not just the element itself.

This behavior ensures that the background covers the entire screen, creating a consistent and seamless visual experience. It is important to note that while the background styling affects the entire canvas, other properties such as the border remain associated with the

element and behave as expected.
