How to realize the gradual hiding effect of pictures in css

In css, you can use the animation attribute and @keyframes rules to realize the animation of elements fading. Effects, through the @keyframes rule, you can create animations.

The principle of creating animation is to gradually change one set of CSS styles into another set of styles. You can change this set of CSS styles multiple times during the animation.

Specify the time when the change occurs as a percentage, or through the keywords "from" and "to", which are equivalent to 0% and 100%. 0% is the start time of the animation, 100% is the end time of the animation. For best browser support, you should always define 0% and 100% selectors.

The syntax of the animation attribute is as follows:

animation: name duration timing-function delay iteration-count direction;
