Article Introduction：The loading speed of web pages can be improved by optimizing HTML. Specific methods include: 1. Reduce the HTML file size, delete redundant code, spaces and comments, simplify tag attributes and use HTML compression tools; 2. Correctly use semantic tags such as, ,, to avoid abuse and deep nested structures; 3. Delay loading non-critical content, such as the image using the loading="lazy" attribute, non-top-screen content is loaded in or dynamically inserted, and third-party scripts are placed at the bottom or asynchronously; 4. Reduce redirection and external requests, merge CSS and JS files, inline key CSS, and avoid unnecessary external fonts and scripts. These methods are detailed but practical and can significantly improve performance.

Article Introduction：HTML attributes are the way to add extra information to HTML tags, used to configure elements or adjust their behavior. Common attributes include class, id, src, alt, placeholder, etc. They are written in the start tag in the form of name="value", such as href specifying the link address, and alt provides alternative text for the image. Attributes are widely used, such as required to set the input box, triggering JS functions (onclick), and boolean attributes (disabled, checked) to take effect without a value. When using it, you should use quotes to wrap the attribute value, especially if it contains spaces or special characters; specific attributes are only applicable to the corresponding tag; custom

Article Introduction：When optimizing web page performance, you need to pay attention to HTML structure and volume control to improve loading speed and rendering efficiency. First, you should control the size of HTML files, avoid redundant tags, use semantic tags, delete comments, spaces and redundant attributes, and compress HTML through tools such as html-minifier; secondly, reduce the number of DOM nodes, keep the number of page nodes within 1500, use CSS casing and inheritance to reduce the style complexity, and clean up the dynamically generated zombie nodes; again, optimize the key rendering path, reasonably place CSS and JS, use defer or async to load scripts, and load key resources in advance; finally, reasonably adopt server-side rendering (SSR) or static generation (SSG), combining the cache mechanism and streaming rendering step by step

Article Introduction：There are two main ways to create a button in HTML: use tags or. 1. The tag is more intuitive and rich in features, and supports nested text, pictures and other HTML content, suitable for most modern web scenarios; 2. It is suitable for simple button requirements, especially common in traditional forms, but does not support nested HTML content; 3. When adding functions to buttons, it is recommended to separate logic and structure through JavaScript event listeners; 4. Button types include buttons (normal buttons), submit (submit buttons) and reset (reset buttons), and should be selected correctly according to their purpose to ensure the expected behavior. Only by selecting the tags reasonably and combining CSS styles and JS interactions can we build beautiful and practical buttons.
