What is CSS used for?
CSS is a computer language used to express document styles such as HTML (an application of Standard Generalized Markup Language) or XML (a subset of Standard Generalized Markup Language).
CSS is mainly used to design the style of web pages and beautify web pages; it can not only statically modify web pages, but also dynamically format various elements of web pages in conjunction with various scripting languages.
CSS can perform pixel-level precise control over the layout of element positions in web pages, supports almost all font size styles, and has the ability to edit web page objects and model styles.
Using CSS technology when making the homepage can effectively achieve more precise control over the layout, fonts, colors, backgrounds and other effects of the page.
As long as you make some simple modifications to the corresponding code, you can change the appearance and format of different parts of the same page, or web pages with different numbers of pages.
Its function can be achieved:
(1) It can be used on almost all browsers.
(2) Some functions that had to be implemented through image conversion in the past can now be easily implemented using CSS, thereby downloading the page faster.
(3) Make the fonts on the page more beautiful and easier to arrange, making the page truly pleasing to the eye.
(4) You can easily control the layout of the page.
(5) You can update the styles and formats of many web pages at the same time, no longer need to update page by page. All web page styles on the site can be controlled using a CSS file. As long as the corresponding lines in the CSS file are modified, all pages of the entire site will change accordingly.
