The difference between css html

In recent years, web development has become increasingly popular, and people need more and more web applications and websites. As two important technologies for web development, CSS and HTML are often mentioned. Many people are confused about the difference between CSS and HTML, so this article will discuss their differences in detail.

HTML: A language that describes content and structure

HTML is a markup language used to describe the content and structure of Web pages. It contains tags that surround text, images, and other elements to make them more readable while defining the structure of the page. The HTML markup language uses characters such as angle brackets and slashes to represent tags, such as <h1> and </h1>, <p> and </p>. HTML tags define and organize content into elements such as headings, paragraphs, paragraphs, lists, links, etc. so that browsers can display web page content correctly. HTML is primarily used for the creation, structure, and content presentation of Web pages.

HTML5 adds some new language features to make it easier to handle multimedia content, such as playing video, audio, etc. HTML5 also enables web applications to transform from simple static web pages to applications containing rich content such as games, music, and videos.

CSS: A language for controlling style and layout

CSS is a language that describes the style and layout of Web pages. Its full name is "Cascading Style Sheets". CSS defines the appearance and behavior of each element on a website or application through a set of rules. It is a language that describes styles, which can be used to change the color, size, shape, position, etc. of various elements on a website or application. CSS is often used for beautification, layout, and typography so that web pages can appear the way we want them to.

Unlike HTML, CSS does not contain the content itself. It only controls the visual presentation of content, such as font size, color, position, arrangement, etc. CSS enables developers to specify styles quickly and directly without the time-consuming and laborious process of writing and applying separate style sheets by hand. It can also be applied to print styling and mobile application development.

CSS Frameworks and Preprocessors

In addition to pure CSS languages, there are also CSS frameworks and preprocessors. CSS frameworks are designed for rapid development of web applications, including Bootsrap, Materialize, Foundation, etc. These frameworks provide a set of UI components such as navigation bars, buttons, tables, etc., as well as default styles. This allows developers to create visually appealing and easy-to-use web applications without writing their own CSS stylesheets.

The preprocessor is a tool that extends CSS into programmable languages, including Sass, Less, etc. Developers use preprocessors to write more expressive CSS. Preprocessors simplify the CSS development process by using variables, functions, nesting, and other programming language-like syntax in style sheets.

Summary

HTML is a language used to describe the content and structure of Web pages, and CSS is a language used to describe the style and layout of Web pages. HTML defines the content and structure of a web page, and CSS controls the page's appearance and behavior. Although HTML and CSS have many differences, they are both important technologies that are integral to web development. This also shows that web development requires mastering both HTML and CSS technologies in order to create beautiful, easy-to-use, and feature-rich web applications.
