This time I will bring you the use of CSS to realize table tennis fighting animation, and what are the precautions about using CSS to realize table tennis fighting animation. The following is a practical case, let's take a look.

Code Interpretation

Define dom, the container contains left racket, small ball and right racket:

<p class="court">
    <p class="left-paddle"></p>
    <p class="ball"></p>
    <p class="right-paddle"></p>
</p>
Copy after login

Centered display:

body {
    height: 100vh;
    display: flex;
    align-items: center;
    justify-content: center;
    background: linear-gradient(silver, dimgray);
}
Copy after login

Adjustment Box model :

* {
    box-sizing: border-box;
}
Copy after login

Draw the ball case:

.court {
    width: 20em;
    height: 20em;
    color: white;
    border: 1em solid currentColor;
}
Copy after login

Draw the left racket:

.court {
    position: relative;
}
.left-paddle
    width: 1em;
    height: calc(50% - 1em);
    background-color: currentColor;
    position: absolute;
    top: 1em;
    left: 1em;
}
Copy after login

Let the left racket move:

.left-paddle {
    animation: left-moving 1s linear infinite alternate;
}
@keyframes left-moving {
    to {
        transform: translateY(100%);
    }
}
Copy after login

Similarly, draw the right racket:

.right-paddle
    width: 1em;
    height: calc(50% - 1em);
    background-color: currentColor;
    position: absolute;
    top: 1em;
    left: 1em;
    bottom: 1em;
    right: 1em;
}
Copy after login

Similarly, draw the right racket:

.right-paddle {
    animation: right-moving 1s linear infinite alternate;
}
@keyframes right-moving {
    to {
        transform: translateY(-100%);
    }
}
Copy after login

Draw the ball:

.ball {
    width: 100%;
    height: 1em;
    border-left: 1em solid currentColor;
    position: absolute;
    left: 2em;
    top: calc(50% - 1.5em);
}
Copy after login

Let the ball move:

.ball {
    animation: bounce 1s linear infinite alternate;
}
@keyframes bounce {
    to {
        left: calc(100% - 3em);
    }
}
Copy after login

Finally, refactor the left and right shooting code and merge the common attributes:

.left-paddle,
.right-paddle {
    width: 1em;
    height: calc(50% - 1em);
    background-color: currentColor;
    position: absolute;
    animation: 1s linear infinite alternate;
}
.left-paddle {
    top: 1em;
    left: 1em;
    animation-name: left-moving;
}
.right-paddle {
    bottom: 1em;
    right: 1em;
    animation-name: right-moving;
}
Copy after login
