Use CSS to create dotted borders, just set the border attribute to dotted. For example, "border:3pxdotted#000" can add a 3-pixel-wide black dot border to the element. By adjusting the border-width, the size of the point can be changed. The wider borders produce larger points. You can set dotted borders for a certain side, such as "border-top:2pxdottedred". Dotted borders are suitable for block-level elements such as div and input. They are often used in focus states or editable areas to improve accessibility. Pay attention to color contrast. At the same time, different from dashed's short-line style, dotted presents a circular dot shape. This feature is widely used in all mainstream browsers.

To create a glass mimicry effect of CSS, you need to use backdrop-filter to achieve background blur, set a translucent background such as rgba(255,255,255,0.1), add subtle borders and shadows to enhance the sense of hierarchy, and ensure that there is enough visual content behind the elements; 1. Use backdrop-filter:blur(10px) to blur the background content; 2. Use rgba or hsla to define the transparent background to control the degree of transparency; 3. Add 1pxsolidrgba(255,255,255,0.3) borders and box-shadow to enhance the three-dimensionality; 4. Ensure that the container has rich backgrounds such as pictures or textures to present a blurred penetration effect; 5. It is compatible with old browsers

To change the CSS list style, first use list-style-type to change the bullet or numbering style. 1. Use list-style-type to set the bullet of ul to disc, circle or square, and the number of ol is decimal, lower-alpha, upper-alpha, lower-roman or upper-roman. 2. Remove the tag completely with list-style:none. 3. Use list-style-image:url('bullet.png') to replace it with a custom image. 4. Use list-style-position:in

There are two main ways to implement dark mode: one is to use prefers-color-scheme media to query automatically to adapt system preferences, and the other is to add manual switching function through JavaScript. 1. Use prefers-color-scheme to automatically apply dark themes according to the user system. There is no need for JavaScript, just define the styles in the media query; 2. To achieve manual switching, you need to define light-theme and dark-themeCSS classes, add toggle buttons, and use JavaScript to manage the theme status and localStorage to save user preferences; 3. You can combine both to read localSt first when the page is loaded.

To add box shadows, use box-shadow attribute; 1. The basic syntax is box-shadow: horizontal offset vertical offset blur radius expansion radius shadows in color; 2. The first three values are required, the rest are optional; 3. Use rgba() or hsla() to achieve transparent effect; 4. The positive expansion radius expands shadows and the negative value is reduced; 5. Multiple shadows can be added by commas separation; 6. Overuse should be avoided to ensure that visibility is tested on different backgrounds; this attribute is well supported by the browser, and reasonable use can improve the design texture.
