HTML (Hypertext Markup Language) is a markup language used to create web pages. In this article, we will cover how to write HTML code.

Create HTML document structure

To create an HTML document, you need to use the following code as a frame:

<!DOCTYPE html>
<html>
  <head>
    <title>页面标题</title>
  </head>
  <body>
    页面内容
  </body>
</html>

: This is the document type declaration of HTML5 and must be the first line of the document.
: The root element contains the content of the entire web page.
: Some elements and information need to be added, these elements include <title></title>, <meta> , <link>, etc.
<title></title> : Define the title of the web page, which will be displayed on the browser tab.
: Defines the main part of the web page, including most of the page content.

Add basic elements

HTML uses tags to define elements, and the tags are located in angle brackets, such as <p></p>. Here are some basic elements:

<p></p> : Paragraph.
<a></a>: Link, the href attribute points to the URL address of the link.
<img alt="How to write html code" >: Image, the src attribute points to the URL address of the image.
<header></header> : Add content at the top of the web page.
<footer></footer> : Add content to the bottom of the web page.
<div>: The document is divided into block-level areas and is the most commonly used container element in HTML. <li> <code><span></span> : Inline tags that can be used to add small marks to the text.

Add styles

You can use CSS to add styles. CSS is a cascading style sheet used to add styles to HTML elements. There are three ways to reference CSS:

Internal style sheet: Place the style directly in the HTML document and use the <style></style> tag definition.

<!DOCTYPE html>
<html>
  <head>
    <style>
      p { color: red; }
    </style>
  </head>
  <body>
    <p>这是一个红色的段落</p>
  </body>
</html>

External style sheet: Place the style in a .css file and reference it in the HTML using the <link> tag .

<!DOCTYPE html>
<html>
  <head>
    <link rel="stylesheet" type="text/css" href="样式表名称.css">
  </head>
  <body>
    <p>这是一个样式表中定义的段落</p>
  </body>
</html>

Inline styles: Place styles in the style attribute of the HTML element.

<!DOCTYPE html>
<html>
  <head>
  </head>
  <body>
    <p style="color:red;">这是一个红色的段落</p>
  </body>
</html>

Adding additional elements and attributes

There are also some elements and attributes that can be added to an HTML document to make it richer and more interesting.

<video></video>: Video content, used to add videos to web pages.
<audio></audio>: Audio content, used to add music to web pages.
<canvas></canvas> : Canvas for creating interactive graphics and animations.
<input> : Input box, used to obtain data entered by the user.
<select></select> : Drop-down menu used to provide option selection.

Summary

HTML is the most basic component of modern web pages. Writing HTML code requires understanding common elements, attributes, and styles. For beginners, the above HTML construction code provides certain guidance and help, but understanding the principles and methods of code writing requires long-term practice and mastery.
