Jun 24, 2016 pm 12:20 PMAs soon as I move the mouse away from the navigation bar, the drop-down menu disappears and the mouse cannot be moved over the menu at all. What should I do? ? ? Please God, it is best to use a simpler method
Reply to the discussion (solution)
Add a timer to the "Hide the drop-down menu" area and specify the amount of time before hiding it.
Then when the mouse moves to the drop-down menu, clear the timer.
The above is the idea, just write the specific code yourself, it is quite simple.

I don’t know what happened to the one I wrote. When the mouse is moved to the menu ul, it shows that it is an onmouseout event? ? What's going on? ?

Is there any specific code?The drop-down menu must be wrapped in the main menu
The mouse has moved to a blank space.
<ul> <li><a>MENU</a> <ul> <li><a>LIST</a></li> </ul> </li></ul>The reason why it disappears before it can be moved is because there is a blank space between the hyperlink text and the sub-navigation. When moving, it passes through the blank area first. If you are familiar with using the inspect element function of the Chrome browser, you can check it out. The solution is to set a padding value for the text of the main navigation hyperlink. For example, set #nav a {padding:10px 20px;}, and the margin value is 0
Put the drop-down menu into the corresponding navigation bar label. Next
There should be no problem if you use JQUERY's hide
Just write an onmouseover event for the drop-down menu page
Thank you for your enthusiastic answers. My problem has been solved

The key to keep up with HTML standards and best practices is to do it intentionally rather than follow it blindly. First, follow the summary or update logs of official sources such as WHATWG and W3C, understand new tags (such as) and attributes, and use them as references to solve difficult problems; second, subscribe to trusted web development newsletters and blogs, spend 10-15 minutes a week to browse updates, focus on actual use cases rather than just collecting articles; second, use developer tools and linters such as HTMLHint to optimize the code structure through instant feedback; finally, interact with the developer community, share experiences and learn other people's practical skills, so as to continuously improve HTML skills.

The reason for using tags is to improve the semantic structure and accessibility of web pages, make it easier for screen readers and search engines to understand page content, and allow users to quickly jump to core content. Here are the key points: 1. Each page should contain only one element; 2. It should not include content that is repeated across pages (such as sidebars or footers); 3. It can be used in conjunction with ARIA properties to enhance accessibility. Usually located after and before, it is used to wrap unique page content, such as articles, forms or product details, and should be avoided in, or in; to improve accessibility, aria-labeledby or aria-label can be used to clearly identify parts.

To reduce the size of HTML files, you need to clean up redundant code, compress content, and optimize structure. 1. Delete unused tags, comments and extra blanks to reduce volume; 2. Move inline CSS and JavaScript to external files and merge multiple scripts or style blocks; 3. Simplify label syntax without affecting parsing, such as omitting optional closed tags or using short attributes; 4. After cleaning, enable server-side compression technologies such as Gzip or Brotli to further reduce the transmission volume. These steps can significantly improve page loading performance without sacrificing functionality.

To create a basic HTML document, you first need to understand its basic structure and write code in a standard format. 1. Use the declaration document type at the beginning; 2. Use the tag to wrap the entire content; 3. Include and two main parts in it, which are used to store metadata such as titles, style sheet links, etc., and include user-visible content such as titles, paragraphs, pictures and links; 4. Save the file in .html format and open the viewing effect in the browser; 5. Then you can gradually add more elements to enrich the page content. Follow these steps to quickly build a basic web page.

To create an HTML checkbox, use the type attribute to set the element of the checkbox. 1. The basic structure includes id, name and label tags to ensure that clicking text can switch options; 2. Multiple related check boxes should use the same name but different values, and wrap them with fieldset to improve accessibility; 3. Hide native controls when customizing styles and use CSS to design alternative elements while maintaining the complete functions; 4. Ensure availability, pair labels, support keyboard navigation, and avoid relying on only visual prompts. The above steps can help developers correctly implement checkbox components that have both functional and aesthetics.

It is a semantic tag used in HTML5 to define the bottom of the page or content block, usually including copyright information, contact information or navigation links; it can be placed at the bottom of the page or nested in, etc. tags as the end of the block; when using it, you should pay attention to avoid repeated abuse and irrelevant content.
