Course Introduction：Want to customize the style of text selected by users on the web page? It can be implemented through the ::selection pseudo-element of CSS. ::selection allows setting some properties such as background color, font color, etc. of selected text, but does not support borders or gradient backgrounds. When using it, you can directly apply to specific tags or classes, such as p::selection or .highlight::selection. To ensure compatibility, it is recommended to add the -webkit- prefix to adapt to more devices. In addition, different selectors can be used to set different selection effects for various elements to improve the overall aesthetics of the page and user experience.
