Cascading style list (CSS) is a language that describes the appearance of documents developed in a markup language, such as HTML. It enables you to specify the appearance of HTML elements, such as textual content, tables, and pictures.
Originally created in 1996, CSS is a recommendation of the World Wide Web Consortium (W3C). The primary version of CSS was launched in December 1996.
Advantages of CSS:
Some great benefits of CSS will be attributed to the fact that it separates the contents (HTML code) from presentation (visual styling). This makes it easier for a Web developer to improve the look of a site by making changes to a central file rather than to each page.
How CSS Works:
Cascading down style bedding are a group of rules that determine the appearance of an HTML CODE element, such as the font or size of a proceeding. These guidelines are identified by the selector that’s placed between ugly brackets. This selector identifies which CODE element the style will impact, and it provides property values and also other design facts.
