What is CSS?

CSS is the abbreviation of Cascading Style Sheet, which is translated into Chinese as "cascading style sheet". It is a markup language that controls the style of web pages and allows the separation of style code from web content.

To put it simply, the introduction of CSS is to make HTML language better adapt to the artistic design of the page.

CSS was approved and recommended by W3C in 1996. The introduction of CSS immediately led to one new and most exciting part of web design, and excellent pages designed using CSS emerge one after another.

W3C is the abbreviation of World Wide Web Consortium, which is translated into Chinese as "World wide Web Alliance". It is a Web standardization organization. W3C not only formulates CSS standards, but also formulates more than 200 Web technical standards, such as HTML, XML and so on.

CSS is based on HTML language and provides rich formatting functions, such as font, color, background and overall typesetting, and web designers can set different styles for a variety of visual browsers, including monitors, printers, tablets, mobile phones and other mobile devices.

CSS is mainly used to design the style of the web page and beautify the web page; it can not only modify the web page statically, but also format the elements of the web page dynamically with various scripting languages.

CSS can accurately control the layout of elements in a web page at the pixel level, support almost all font size styles, and have the ability to edit web objects and model styles.

(2) greatly reduce the page code, improve page loading speed, reduce bandwidth costs: by using CSS, you do not need to write HTML tag attributes every time, you only need to write the CSS rules of a tag, and apply it to all instances of the tag, so a great reduction in code means a short download time.

(3) easy to maintain: if you want to make global changes, you only need to change the style, and all elements in all pages will be updated automatically.

(4) multiple device compatibility: stylesheets allow you to optimize content for many different types of devices.

(5) the structure is clear, which is more convenient for the search engine. Replace nested tags with HTML that contains only structured content, and search engines will search your content more effectively and may give you a higher ranking.
