Viewport meta tags must be added to ensure that the page is rendered correctly by mobile devices. 2. Using a mobile-first design method, first write basic styles for small screens and then adapt to the large screen through media queries. 3. Using Flexbox or Grid to create a flexible responsive grid layout. 4. Ensure the image is adaptively scaled on different devices through max-width:100%, ensuring that the image is adaptively scaled on different devices. 5. Prioritize relative units such as rem, %, vw rather than fixed pixel values. 6. Using browser development tools and combining real devices for multi-scene testing. 7. Keep the layout simple and accessible, use semantic HTML and ensure that the touch area is large enough, and ultimately achieve a responsive web layout that performs well on all devices.

vw and vh units achieve responsive design by associating element sizes with viewport width and height; 1vw is equal to 1% of viewport width, and 1vh is equal to 1% of viewport height; commonly used in full screen area, responsive fonts and elastic spacing; 1. Use 100vh or better 100dvh in the full screen area to avoid the influence of the mobile browser address bar; 2. Responsive fonts can be limited with 5vw and combined with clamp (1.5rem, 3vw, 3rem) to limit the minimum and maximum size; 3. Elastic spacing such as width:80vw, margin:5vhauto, padding:2vh3vw, can make the layout adaptable; pay attention to mobile device compatibility, accessibility and fixed width content conflicts, and it is recommended to give priority to using dvh first;

To style tags, you need to use CSS like ordinary HTML elements. 1. You can improve readability by setting basic styles such as background, color, font, etc.; 2. You can use the value attribute to perform conditional styles, such as displaying different colors according to "in-stock" or "out-of-stock"; 3. You can combine class class names to achieve more flexible style control, which is easy to reuse; 4. You can also add hover effects and other interactions to enhance user experience, and ultimately achieve the unity of semantics and vision.

To delete stored procedures in other databases, DROPPROCEDUREIFEXISTSdatabase_name.procedure_name; 4. ALTERROUTINE or CREATEROU is required to perform this operation.

srcset and sizes attributes jointly optimize responsive image loading. 1. srcset provides image options of different sizes or resolutions, such as "image-400w.jpg400w" according to width or "image-2x.jpg2x" according to pixel density; 2. Sizes defines the layout width of the image under different viewports, such as "(max-width:600px)100vw" means that the small screen is full of full width; 3. The browser combines the two to select the most suitable image to ensure the balance between performance and display quality; 4. Fixed size pictures can be used with srcset and 1x/2x, and fluid layout requires srcset to add sizes; 5. Always retain src as a downgrade solution and add alt text

Set the maximum value such as 2.5rem. The final font is smoothly scaled and readable under different screen sizes, and can be completed with one line of code.

Use HTML to create a structure containing tag buttons and content panels, and correspond to ids through data-tab attributes; 2. Use CSS to set styles and hide inactive states, and control display through active classes; 3. Use JavaScript to add click events to the buttons, switch active classes to realize tag switching function, and ensure that the buttons and corresponding content are displayed in a coordinated manner. This component works together through HTML, CSS and JavaScript to achieve simple and efficient tab switching effects.
