<p> HTML tags are the basis of web page structure, and they are used to tell the browser how to display content. Simply put, HTML tags are like a tagging system. Through these tags, you can define whether a text is a title, paragraph, link, or image, etc.
What are HTML tags?
<p> HTML (HyperText Markup Language) is a markup language, not a programming language. It consists of a series of elements , and each element is usually composed of a pair of tags wrapped content, such as<p></p> is a paragraph tag, 
<p> Tags themselves do not appear in the browser, but they affect how the content is displayed. For example:<h1>This is a big title</h1> <p>This is a paragraph. </p><p> The above code will appear on the page as a large title and a paragraph, and the user cannot see the
<h1> or <p> tag names, but the browser will format the content correctly based on them. 
What are the common HTML tags?
<p> Here are some common HTML tags and their uses:<ul><li><h1> to <h6> : Title tag, the smaller the number, the larger the font<li> <p> : paragraph<li> <a> : Hyperlink, often used with href attribute, such as <a href="https://example.com">點(diǎn)擊我</a><li> <img alt="What are HTML tags and how do they work?" > : Insert image, commonly used src and alt attributes<li> <ul> , <ol> and <li> : Unordered lists, ordered lists and list items<li> <div> and <span> : General-purpose containers for layout and style control<p> These tags form the basic skeleton of web page content. All the web content you see is composed of various HTML tags.How does HTML tag work?
<p> When you open a web page, the browser will read the HTML file sent from the server and parse the content in the order of tags. Every time a tag is encountered, the browser knows what to do:<ul><li> When encountering<h1> , display the content as the main title.<li> When encountering <p> , treat it as an ordinary paragraph and automatically add a little up and down spacing.<li> Render it into a clickable blue link when encountering <a><p> If you write the wrong tag or miss the end tag, the browser can sometimes automatically complete it, but it is best to write it strictly in accordance with the specifications. Otherwise, it may cause typography disorders or abnormal functions.How to get started with HTML tags?
<p> It's actually very simple. You only need a text editor (such as notepad) and a browser to start writing. The steps are as follows:<ul><li> Create a new.html file, for example, index.html<li> Write basic structure: <!DOCTYPE html>
<html>

</head>
<body>
<h1>Hello, World!</h1>
<p>This is my first page. </p>
</body>
</html><ul><li> Double-click this file and open it in a browser to see the effect
<p> This method does not require any complicated tools and is suitable for beginners to start.
