    How to style a link based on its state (:link, :visited, :hover, :active)?
    In web development, the style of linking different states can be individually set through the pseudo-class of CSS to improve the user experience. 1. First understand the meaning of each pseudo-class::link means no link is visited, :visited means the link has been visited, :hover means the hover state, and :active means the instant of clicking; 2. Writing pseudo-classes in LVHA order ensures the correct priority, and the order should be: link, :visited, :hover, :active; 3. Style suggestions include avoiding the use of similar colors to distinguish states, combining text decoration to enhance recognition, and pay attention to the differences in behavior of mobile:hover; 4.

  • How to center an item both horizontally and vertically using Flexbox?
    How to center an item both horizontally and vertically using Flexbox?
    To center elements horizontally and vertically in the container, 1. Set the container as a Flex container and use display:flex; 2. Use justify-content:center to center the main axis direction; 3. Use align-items:center to center the cross axis direction; if the container has multiple child elements, it will be arranged horizontally and centered overall by default. If you need vertical arrangement, you can combine flex-direction:column and keep the alignment attribute unchanged, and the centering effect can be achieved.
