How CSS works

CSS is a language that defines style structures such as fonts, colors, locations, etc., and is used to describe the formatting and reality of information on web pages. CSS styles can be stored directly in HTML pages or in separate style sheet files.

Either way, the stylesheet contains rules for applying styles to elements of the specified type. When used externally, style order rules are placed in an external style order document with the file extension _ css.

Style rules are formatting instructions that can be applied to elements in a web page, such as text paragraphs or links. A style rule consists of one or more style properties and their values. The internal style sheet is placed directly in the web page, the external style sheet is saved in a separate document, and the web page links the external style sheet through a special tag.

The "cascading" in the name CSS indicates how style order rules are applied to HTML document elements. Specifically, the styles in the CSS stylesheet form a hierarchy, and more specific styles override generic styles. The priority of the style rules is determined by CSS according to this hierarchy, thus achieving the cascading effect.
