css (Cascading Style Sheets)

css is a standard style sheet language used to describe the presentation of web pages (such as the position of web page elements , size, color, etc.).

CSS, HTML and JavaScript are considered the three basic languages ​​for web front-end design, among which:

• HTML is responsible for building the basic structure of web pages;

• CSS is responsible for designing the performance effects of web pages;

• JavaScript is responsible for developing the interactive effects of web pages.

The main function of CSS is to define the style of the web page (beautify the web page) and precisely control the position, font, color, background and other attributes of the elements in the web page. CSS can not only statically modify web pages, but can also work with JavaScript to dynamically modify the styles of elements in web pages. CSS is supported by almost all browsers on the market.

Server-side development language

The server-side development language refers to the programming language used to assist the work of the Web server. It can also be said to be an extension of the functions of the Web server and Plug-ins work together on the web server.

When the Web server receives an HTTP request, it will respond to the client browser with the prototype of the file requested by the user under the server. If it is a file that the browser can interpret, such as HTML or images, the browser will interpret it directly and display the result to the user. If the file format is not recognized by the browser, the browser will interpret it as a download and prompt the user to download or open it.

If users want to get dynamic response results, they must entrust server-side scripting programming language to complete it. For example, user registration, information query and other functions in the web page all need to operate on the data in the server-side database.

The Web server itself does not have the function of operating the database, so it is necessary to entrust server script programming to complete the work of adding and querying the database, and generate the processed results into HTML that the browser can interpret. The content is then sent to the client browser through the web server.

Server-side scripting is related to Internet server programming, so that it can deliver more dynamic website content. Through server-side programming, you can dynamically edit, modify, or add web content. Can respond to user-submitted queries or data from HTML, access the data or database, and return the results to the browser. You can also access files or XML data and return the results to the browser, convert the XML to HTML, and return the results to the browser. You can also customize pages for different users, improve page usability, provide secure access control for different web pages, design different outputs for different types of browsers, and so on. It is a tool that truly realizes business processing capabilities and is also a platform for users to work.
