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.

The positive expansion radius expands shadows and the negative value is reduced; 5. Multiple shadows can be added by commas separation; 6.
