How to make a web page with html

HTML is one of the most basic and important languages ​​in the field of web design. It is a markup language that allows developers to create well-structured, uniformly styled, and easy-to-maintain websites.

To make a good-looking and useful website, you need to master the following steps:

1. Establish the file structure

Before you start writing HTML, you need to Create folders and files first. It is recommended to save HTML files in a separate directory for subsequent writing and modification. You can also use a code editor to help write HTML files. For example, Visual Studio Code, Sublime Text, Atom, etc.

2. Learn HTML syntax

HTML is a markup language that describes the various parts and content of a web page through tags and attributes. Tags are surrounded by angle brackets and can be nested, and attributes are used to provide more information to the tag.

For example, to create a basic HTML document, you can use the following code:

    <title>我的网站</title>


    <h1 id="欢迎来到我的网站">欢迎来到我的网站</h1>
    <p>这是我第一个网页</p>

This code defines an HTML document that includes a head and a body tag. In the head tag, we can define the title of the web page, style files, script files, etc. In the body tag, we can add content such as titles, paragraphs, images, etc.

3. Add content

To add content, you can use various HTML tags. For example, to create a paragraph, you can use the p tag:

<p>这是一个段落。</p>

To create a title, you can use h1~h6 tags, for example:

<h1 id="这是一个最大的标题">这是一个最大的标题。</h1>
<h2 id="这是一个稍小的标题">这是一个稍小的标题。</h2>
<h3 id="这是一个更小的标题">这是一个更小的标题。</h3>

To create a link, you can use the a tag, For example:

<a href="http://www.baidu.com">百度一下，你就知道。</a>

To add an image, you can use the img tag, for example:

<img src="/static/imghwm/default1.png" data-src="picture.jpg" class="lazy" alt="我的照片">

Among them, the src attribute specifies the URL of the image, and the alt attribute is a description of the image.

4. Using CSS styles

Although HTML can describe the structure and content of a web page, CSS can provide a more beautiful appearance for the web page. CSS is a stylesheet language that adds style and layout to HTML.

To use CSS, you can add a style sheet file to the HTML document, for example:

    <title>我的网站</title>
    <link rel="stylesheet" type="text/css" href="style.css">


    <h1 id="欢迎来到我的网站">欢迎来到我的网站</h1>
    <p>这是我第一个网页</p>

In the style.css file, you can add style rules, for example:

h1 {
    color: red;
}

p {
    font-size: 20px;
}

This code adds two style rules. The first rule changes the color of the h1 tag to red, and the second rule changes the font size of the p tag to 20 pixels.

5. Debugging and Optimization

When writing HTML web pages, various problems often occur, such as style failure, disordered layout, etc. To reduce these problems, we can use the browser's developer tools to debug and optimize web pages.

Most modern browsers provide developer tools, which can be opened through the F12 key or the right-click menu. Developer tools can be used to inspect and edit DOM, CSS, JavaScript, network requests, and more.

During debugging, you can use the console API to print logs and debugging information. For example, you can use the console.log() method to output debugging information:

console.log("Hello, world!");

6. Compatibility and Accessibility

Finally, pay attention to the compatibility and accessibility of the web page Accessibility. Web pages need to function properly across different browsers and operating systems and need to follow standards and best practices. At the same time, web pages also need to take into account the needs and wants of different users, such as blind people, color blindness, deaf-mute, etc.

To improve the accessibility of web pages, you can use accessibility markup and tools, such as aria tags, HTML5 forms, screen readers, and more.

Summary

HTML is the basis for web page production. It can be used to define the structure and content of web pages. With HTML and CSS, we can create beautiful and useful web pages. To make a good web page, you need to master the syntax and skills of HTML and CSS, and pay attention to compatibility and accessibility.
