html$ usage
HTML stands for Hyper Text Markup Language, which is a language used to create web pages. HTML has a very wide range of application scenarios, from simple traditional web pages to complex websites and applications, all of which can be developed with HTML. This article aims to introduce the basic usage of HTML and some practical skills so that beginners can get started quickly.
- The structure of HTML document
In HTML, file names ending in .html or .htm are usually used as web page files. When you open an HTML page, the browser parses the structure of the HTML document and displays them on the visual interface.
HTML document consists of three main parts: Head, Body and Footer. These parts are composed of HTML tags. The following code shows a simple HTML document example:
<html>
<head>
<title>这里是标题</title>
</head>
<body>
<h1>欢迎使用HTML</h1>
<p>这里是文本内容。</p>
</body>
</html>In the above example, the "" and "" tags are used to represent the entire HTML document, and "
" and "" tags are used to represent the head of the document, where "" and "
" tags define the first-level headings, and the "” and “
” tags define a section of text.- HTML tags
HTML tags are divided into two types: block-level tags and inline tags.
- Block-level tags are tags used to organize document structure. They are usually used to represent paragraphs, titles, lists and other elements in the document. Block-level tags occupy their own line and are automatically spaced within the context. Commonly used block-level tags include:
~
,
,
,- ,
- Inline tags are used to add style and special comments to text. Inline tags are often used to add hyperlinks, emphasize text, change colors, etc. Commonly used inline tags include: , , ,
, , etc.
- , etc.
The following are some commonly used HTML tags:
Tag description
–
Define title
< p> Define paragraph
Define image
- Define unordered list
- Define list items
Define table
Define table rows Define header cell Define table data cells defines a section or paragraph in the document defines sections in the document Define emphasized text Define emphasized text 3. HTML comments Comments are a way in code to describe the intent of the code. You can use "" tags in HTML to include comment content, and the browser will automatically ignore these contents. Here is an example of an HTML comment:`Here is the text
`In the above example, the "" tags are used to comment out the content of the paragraph mark. This will not have any impact on the browser's output, but it can Improve code readability and maintainability. 4. HTML attributes HTML tags can have attributes, which are used to control the behavior and characteristics of the tag. Properties usually include property names and property values, which need to be wrapped in quotes. The following is an HTML hyperlink tag with attributes:
`Visit Baidu`In the above example, "href" is the attribute name, and its attribute value is a URL address, "https://www.baidu.com". This URL address is designated to link to a web page. In addition to "href", there are many other commonly used attributes in HTML, as shown below: Property name Description style defines the style of the element class defines the class name of the element id defines the element ID title defines the title of the element src defines the URL address of the image 5. HTML style HTML markup can use CSS styles to define appearance and layout. CSS refers to Cascading Style Sheets, which is a language used to describe the appearance and layout of web pages. Here's an example that shows how to style HTML text:`Here is red text with a font size of 16px.
`In the above example, the CSS style is included in the tag of the HTML document. Among them, the "p" selector is used to select text, while the "color" and "font-size" properties are used to define the color and font size of the text. 6 Conclusion This article introduces the basic usage of HTML and some practical skills.
