How do I use the and elements to provide a caption for an image?

To get started with HTML quickly, you only need to master a few basic tags to build a web skeleton. 1. The page structure is essential, and, which is the root element, contains meta information, and is the content display area. 2. Use the title. The higher the level, the smaller the number. Use tags to segment the text to avoid skipping the level. 3. The link uses tags and matches the href attributes, and the image uses tags and contains src and alt attributes. 4. The list is divided into unordered lists and ordered lists. Each entry is represented and must be nested in the list. 5. Beginners don’t have to force memorize all tags. It is more efficient to write and check them while you are writing. Master the structure, text, links, pictures and lists to create basic web pages.

Image not displayed is usually caused by a wrong file path, incorrect file name or extension, HTML syntax issues, or browser cache. 1. Make sure that the src path is consistent with the actual location of the file and use the correct relative path; 2. Check whether the file name case and extension match exactly, and verify whether the image can be loaded by directly entering the URL; 3. Check whether the img tag syntax is correct, ensure that there are no redundant characters and the alt attribute value is appropriate; 4. Try to force refresh the page, clear the cache, or use incognito mode to eliminate cache interference. Troubleshooting in this order can solve most HTML image display problems.

The style placement method needs to be selected according to the scene. 1. Inline is suitable for temporary modification of single elements or dynamic JS control, such as the button color changes with operation; 2. Internal CSS is suitable for projects with few pages and simple structure, which is convenient for centralized management of styles, such as basic style settings of login pages; 3. Priority is given to reuse, maintenance and performance, and it is better to split external link CSS files for large projects.
