难点及其实现

滚动条自定义：

.card::-webkit-scrollbar {
width: 4px;

}

.card::-webkit-scrollbar-thumb {
border-radius: 8px;
box-shadow: inset 0 0 5px rgba(0, 0, 0, 0.2);
background: #666666;
}

.card::-webkit-scrollbar-thumb:hover {
background: #333333;
}

鼠标点击样式

样式图

逻辑

每次点击的时候先把鼠标位置赋值给:root,然后隔100ms出现一个圈，达到类似水波的样式

const clickFun = (event) => {
    document.documentElement.style.setProperty('--mouseX', event.clientX + 'px')
    document.documentElement.style.setProperty('--mouseY', event.clientY + 'px')
    const circle1 = document.createElement('div');
    circle1.className = 'firstCircle'
    document.body.appendChild(circle1);
    const circle2 = document.createElement('div');
    circle2.className = 'secondCircle'
    const circle3 = document.createElement('div');
    circle3.className = 'thirdCircle'
    setTimeout(() => {
        document.body.appendChild(circle2);
    }, 100)
    setTimeout(() => {
        document.body.appendChild(circle3);
        document.body.removeChild(circle1);
    }, 200); // 1000ms = 1s
    setTimeout(() => {
        document.body.removeChild(circle2);
    }, 300); // 1000ms = 1s
    setTimeout(() => {
        document.body.removeChild(circle3);
    }, 400); // 1000ms = 1s
} 

代码实现
