					The 
 element is used in HTML to define the main content of a web page. This content should be unique to the document and should not appear in the sidebar, navigation bar, or footer. It helps developers and assistive technologies such as screen readers to identify the core content of the page and improve accessibility. For example, screen reader users can jump directly to the  section through shortcut keys, and browsers can also use it to quickly locate related content. In addition,  improves code readability and maintenance, so that the main content is clearly separated from other layout parts. Although search engines will not improve page rankings just because of the use of , it helps clear semantic structure and facilitates crawlers to understand page content. Usually  contains the most important SEO text and media, and should be avoided to be nested within elements such as , , , , or . As a block-level element,  is often used to wrap central articles or product descriptions, and is suitable for Flexbox or Grid layouts, and is designed in conjunction with CSS style. The basic HTML structure includes ,  and , and modern browsers support this tag. 


 The <main></main> element in HTML is used to define the main content of a webpage. This content should be unique to the document and not appear in sidebars, navigation bars, or footers. It helps both developers and assistive technologies like screen readers identify the core content of a page. 
 element?" /> Improves Accessibility
 One of the biggest benefits of using <main></main> is how it supports accessibility. Screen readers can jump directly to the main content, skipping over relative elements like navigation menus. This makes browser more efficient for users who rely on assistive tools.
 For example: 
 element?" />
 A screen reader user might activate a shortcut key to go straight to the <main></main> section.
 Browsers with built-in navigation features (like Safari's "Start Typing to Search" function) can use <main></main> to locate relevant content quickly.

 This tag doesn't just help machines — it also makes your code easier to read and maintain by clearly separating the primary content from other parts of the layout.
 SEO and Semantic Clarity
 While search engines don't necessarily rank pages higher just for using <main></main> , it contributes to better semantic structure. Clean, meaningful markup helps crawlers understand what your page is about. 
 element?" /> Consider this:

 The <main></main> section often contains the most important text and media for SEO.
 Proper use of semantic tags (like <main></main> , <header></header> , <footer></footer> , etc.) creates a clearer outline of your page, which may improve how your content is indexed.

 It's worth noting that there should only be one <main></main> element per page, and it shouldn't be nested inside elements like <article></article> , <aside></aside> , <footer></footer> , <header></header> , or <nav></nav> .
 Practical Usage and Styling
 You can treat <main></main> like any other block-level element. It's commonly used as a container for the central part of a layout, making it a good candidate for styling with CSS.
 Here are some typical uses:

 Wrapping the central article or product description
 Applying styles such as padding, margin, or background color specifically to the main area
 Using it alongside layout techniques like Flexbox or Grid

 A basic HTML structure might look like this:
 <body>
  <header>...</header>
  <main>
    <!-- Main content here -->
  </main>
  <footer>...</footer>
</body>
 Since it's supported in all modern browsers, you can safely use <main></main> without worrying about compatibility issues.
 Basically that's it.

								Adding drag and drop functionality using the HTML5 Drag and Drop API.
								Jul 05, 2025 am	 02:43 AM
								The way to add drag and drop functionality to a web page is to use HTML5's DragandDrop API, which is natively supported without additional libraries. The specific steps are as follows: 1. Set the element draggable="true" to enable drag; 2. Listen to dragstart, dragover, drop and dragend events; 3. Set data in dragstart, block default behavior in dragover, and handle logic in drop. In addition, element movement can be achieved through appendChild and file upload can be achieved through e.dataTransfer.files. Note: preventDefault must be called
							
														
								
									
								
								Getting user location with HTML5 geolocation API
								Jul 04, 2025 am	 02:03 AM
								To call GeolocationAPI, you need to use the navigator.geolocation.getCurrentPosition() method, and pay attention to permissions, environment and configuration. First check whether the browser supports API, and then call getCurrentPosition to obtain location information; the user needs to authorize access to the location; the deployment environment should be HTTPS; the accuracy or timeout can be improved through configuration items; the mobile behavior may be limited by device settings; the error type can be identified through error.code and given corresponding prompts in the failed callback to improve user experience and functional stability.
							
														
								
									
								
								Using ARIA attributes with HTML5 semantic elements for accessibility
								Jul 07, 2025 am	 02:54 AM
								The reason why ARIA and HTML5 semantic tags are needed is that although HTML5 semantic elements have accessibility meanings, ARIA can supplement semantics and enhance auxiliary technology recognition capabilities. For example, when legacy browsers lack support, components without native tags (such as modal boxes), and state updates need to be dynamically updated, ARIA provides finer granular control. HTML5 elements such as nav, main, aside correspond to ARIArole by default, and do not need to be added manually unless the default behavior needs to be overridden. The situations where ARIA should be added include: 1. Supplement the missing status information, such as using aria-expanded to represent the button expansion/collapse status; 2. Add semantic roles to non-semantic tags, such as using div role to implement tabs and match them
							
														
								
									
								
								Securing HTML5 web applications against common vulnerabilities
								Jul 05, 2025 am	 02:48 AM
								The security risks of HTML5 applications need to be paid attention to in front-end development, mainly including XSS attacks, interface security and third-party library risks. 1. Prevent XSS: Escape user input, use textContent, CSP header, input verification, avoid eval() and direct execution of JSON; 2. Protect interface: Use CSRFToken, SameSiteCookie policies, request frequency limits, and sensitive information to encrypt transmission; 3. Secure use of third-party libraries: periodic audit dependencies, use stable versions, reduce external resources, enable SRI verification, ensure that security lines have been built from the early stage of development.
							
														
								
									
								
								Integrating CSS and JavaScript effectively with HTML5 structure.
								Jul 12, 2025 am	 03:01 AM
								HTML5, CSS and JavaScript should be efficiently combined with semantic tags, reasonable loading order and decoupling design. 1. Use HTML5 semantic tags, such as improving structural clarity and maintainability, which is conducive to SEO and barrier-free access; 2. CSS should be placed in, use external files and split by module to avoid inline styles and delayed loading problems; 3. JavaScript is recommended to be introduced in front, and use defer or async to load asynchronously to avoid blocking rendering; 4. Reduce strong dependence between the three, drive behavior through data-* attributes and class name control status, and improve collaboration efficiency through unified naming specifications. These methods can effectively optimize page performance and collaborate with teams.
							
														
								
									
								
								Using HTML5 Semantic Elements for Page Structure
								Jul 07, 2025 am	 02:53 AM
								Using HTML5 semantic tags can improve web structure clarity, accessibility and SEO effects. 1. Semantic tags such as,,,, and make it easier for the machine to understand the page content; 2. Each tag has a clear purpose: used in the top area, wrap navigation links, include core content, display independent articles, group relevant content, place sidebars, and display bottom information; 3. Avoid abuse when using it, ensure that only one per page, avoid excessive nesting, reasonable use and in blocks. Mastering these key points can make the web page structure more standardized and practical.
							
														
								
									
								
								HTML5 video not playing in Chrome
								Jul 10, 2025 am	 11:20 AM
								Common reasons why HTML5 videos don't play in Chrome include format compatibility, autoplay policy, path or MIME type errors, and browser extension interference. 1. Videos should be given priority to using MP4 (H.264) format, or provide multiple tags to adapt to different browsers; 2. Automatic playback requires adding muted attributes or triggering .play() with JavaScript after user interaction; 3. Check whether the file path is correct and ensure that the server is configured with the correct MIME type. Local testing is recommended to use a development server; 4. Ad blocking plug-in or privacy mode may prevent loading, so you can try to disable the plug-in, replace the traceless window or update the browser version to solve the problem.
							
														
								
									
								
								Embedding video content using the HTML5 `` tag.
								Jul 07, 2025 am	 02:47 AM
								Embed web videos using HTML5 tags, supports multi-format compatibility, custom controls and responsive design. 1. Basic usage: add tags and set src and controls attributes to realize playback functions; 2. Support multi-formats: introduce different formats such as MP4, WebM, Ogg, etc. through tags to improve browser compatibility; 3. Custom appearance and behavior: hide default controls and implement style adjustment and interactive logic through CSS and JavaScript; 4. Pay attention to details: Set muted and autoplay to achieve automatic playback, use preload to control loading strategies, combine width and max-width to achieve responsive layout, and use add subtitles to enhance accessibility.
