HTML code can specify the arrangement and display effects of text, images, audio and other media, truly realizing the design of web pages. The following are the steps and techniques for designing web pages in HTML.

2. HTML tags

Before you start designing a web page, you need to create an HTML file first. HTML files are text files in .txt, .html, or .htm format that can be created in any text editor. Here are some common text editors: Notepad, Sublime Text, Atom, Visual Studio, Dreamweaver, etc.

3. Write HTML code

HTML uses tags or tags to describe the structure, style and content of the document. Common elements in web pages include titles, paragraphs, lists, tables, links, images, etc. Let's introduce the specific tags and attributes below.

1. Image compression

Optimizing images can reduce loading time and reduce the size of web pages. Images can be scaled and optimized using the picture editor.

2. Use CSS style sheet

Adding style definitions to the CSS style sheet can greatly reduce the size of the HTML file.

3. Use JavaScript

Using JavaScript can make your web pages more dynamic and interactive. When writing JavaScript code, you need to ensure that it only runs when necessary.

4. Using media queries

Using media queries can provide different layouts and styles for different devices according to the screen size and resolution of the device.

5. Use compressed files

Using compressed files can compress HTML, CSS and JavaScript files to a smaller size, thereby improving the loading speed of web pages.
