Code Interpretation

Define dom, the container contains 6 elements:

<div>
    <span></span>
    <span></span>
    <span></span>
    <span></span>
    <span></span>
    <span></span>
</div>

Centered display:

body {
    margin: 0;
    height: 100vh;
    display: flex;
    align-items: center;
    justify-content: center;
    background-image: linear-gradient(#555, #222);
}

Draw the wheel circle:

.wheel {
    width: 9em;
    height: 9em;
    font-size: 25px;
    border: 0.4em solid #777;
    border-radius: 50%;
    box-shadow: 0 0 0 0.5em #111;
}

Define the style of the spokes:

.wheel {
    display: flex;
    align-items: center;
    justify-content: center;
}

.wheel span {
    position: absolute;
    width: 8em;
    height: 1em;
    border: 0.1em solid;
    border-color: #ccc transparent;
}

Define variables and draw multiple spokes:

.wheel span {
    transform: rotate(calc((var(--n) - 1) * 30deg));
}

.wheel span:nth-child(1) {
    --n: 1;
}

.wheel span:nth-child(2) {
    --n: 2;
}

.wheel span:nth-child(3) {
    --n: 3;
}

.wheel span:nth-child(4) {
    --n: 4;
}

.wheel span:nth-child(5) {
    --n: 5;
}

.wheel span:nth-child(6) {
    --n: 6;
}

Let the wheel rotate:

.wheel span {
    animation: run 4s linear infinite;
}

@keyframes run {
    to {
        transform: rotate(calc((var(--n) - 1) * 30deg + 360deg));
    }
}

Draw with pseudo elements Draw the lines on the ground:

.wheel {
    position: relative;
}

.wheel::before {
    content: '';
    position: absolute;
    width: 15em;
    height: 0.2em;
    top: 11em;
    background-image: linear-gradient(
            to right,
            silver 0, silver 4em,
            transparent 4em, transparent 5em,
            silver 5em, silver 10em,
            transparent 10em, transparent 12em,
            silver 12em, silver 14em,
            transparent 14em, transparent 15em
        );
}

Finally, let the lines on the ground move to form the effect of wheels moving forward:

.wheel::before {
    background-position: 15em;
    animation: run2 6s linear infinite;
}
@keyframes run2 {
    to {
        background-position: -15em;
    }
}

Done!

实战:vscode中开发一个支持vue文件跳转到定义的插件实战:vscode中开发一个支持vue文件跳转到定义的插件Nov 16, 2022 pm 08:43 PM

vscode自身是支持vue文件组件跳转到定义的,但是支持的力度是非常弱的。我们在vue-cli的配置的下,可以写很多灵活的用法,这样可以提升我们的生产效率。但是正是这些灵活的写法,导致了vscode自身提供的功能无法支持跳转到文件定义。为了兼容这些灵活的写法,提高工作效率,所以写了一个vscode支持vue文件跳转到定义的插件。
