The following are the steps and techniques for designing web pages in HTML.

1. Basic syntax of HTML

The basic structure of HTML language is composed of tags and text. Labels are represented by angle brackets and indicate the beginning or end of a range of an element. There are some attributes you can use in tags, which provide more control over the style and functionality of the element.

2. HTML tags

, , , etc.

2. Create an HTML file

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. Title tag

The title is represented by h1, h2, h3 and other tags in HTML. These tags are used to create the title of the page, with h1 representing the most important content and h6 representing the least important content. The following is the h1 tag:

This is a title

2. Paragraph tag

Paragraphs are represented by p tags in HTML. This tag is used to create paragraphs and natural line breaks. Here is an example:

This is a paragraph.

This is another paragraph that appears on the next line.

3. List tag

In HTML, you can create an unordered list (ul) and an ordered list (ol), and a single option is represented by the li tag. The following is an example of an unordered list:

<li>项目一</li>
<li>项目二</li>
<li>项目三</li>

4. Link tag

4. Apply CSS styles

CSS (Cascading Style Sheets) is used to control the style of the page. CSS can define styles through style sheets (StyleSheet). A style sheet is a set of style rules that apply to various elements of a web page.

Through CSS, you can change the background, font, color, size, position and other characteristics of elements on the page. The following is an example of a CSS style:

body {
    background-color: #f0f0f0;
}
h1 {
    color: red;
    font-size: 24px;
}
p {
    color: blue;
    font-size: 12px;
    font-family: Arial, sans-serif;
}

5. Run the web page

Complete the HTML file and After the CSS style sheet, the web page can be run in a web browser. Save the HTML file to a web server and access the URL in a browser. If you are running a web page on your local computer, you can use a browser to open the HTML file.

6. Optimize the web page

After designing the web page, you also need to optimize it to improve performance and user experience. The following are some common optimization techniques:

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.

in conclusion

HTML is a markup language that provides the foundation for the creation and presentation of Web pages. Create HTML files, write HTML code and CSS stylesheets, and use a browser to view your web pages. Through optimization, you can improve the performance and user experience of your web pages.
