What do you call css?

Cascading style sheets (English: Cascading Style Sheets, abbreviations: CSS;, also known as cascading style lists, cascading style sheets, cascading style sheets, hierarchical style sheets) is a computer language used to add styles (fonts, spacing, colors, etc.) to structured documents (such as HTML documents or XML applications), defined and maintained by W3C. CSS is divided into different levels: CSS1 is now obsolete, CSS2.1 is the recommended standard, and CSS3 is divided into small modules and is being standardized. CSS3 is now supported by most modern browsers, while the next version of CSS4 is still under development.

Features of css language

CSS provides a style description for HTML markup language, defining how the elements in it are displayed. CSS is a breakthrough in the field of Web design. It can be used to modify a small style to update all the page elements associated with it.

In general, CSS has the following characteristics:

Rich style definition

CSS provides a rich document-style appearance, as well as the ability to set text and background properties; allows you to create a border for any element, as well as the distance between the border and other elements, as well as the distance between the border and the content of the element; allows you to change the case, retouching, and other page effects of the text at will.

Easy to use and modify

CSS can define the style in the style attribute of the HTML element, in the header section of the HTML document, or declare the style in a special CSS file for reference by the HTML page. In short, CSS stylesheets can store and manage all style declarations in a unified manner.

In addition, you can categorize elements of the same style, define them with the same style, apply a style to all HTML tags with the same name, or assign a CSS style to a page element. If we want to change the style, we just need to find the appropriate style declaration in the style list to modify it.

Multi-page application

CSS stylesheets can be stored in a separate CSS file so that we can use the same CSS stylesheet in multiple pages. CSS stylesheets theoretically do not belong to any page file and can be referenced in any page file. In this way, the style of multiple pages can be unified.

Cascading

Simply put, cascading is setting the same style multiple times for an element, which uses the last set attribute value. For example, if you use the same set of CSS stylesheets for multiple pages in a site, and some elements of some pages want to use other styles, you can define a separate stylesheet for those styles to apply to the page. These later defined styles will override the previous style settings, and what you will see in the browser is the style effect of the last setting.

Page compression

In websites that use HTML to define page effects, it often requires a large number of or repeated tables and font elements to form text styles of various specifications, which results in a large number of HTML tags, thus increasing the size of the page file. Putting the style declaration separately in the CSS stylesheet can greatly reduce the size of the page, so the time used to load the page will be greatly reduced. In addition, the reuse of CSS stylesheets greatly reduces the size of the page and reduces the download time.
