如何制作一个骨头形状的按钮

Ger*_*ken 21 html css svg css-transitions

我目前正在为我的网站试验一个按钮。我希望它看起来像一个普通的按钮,但是一旦你将它悬停,它就会变成一个骨头(我的网站是关于狗的)。

所以我使用了一个已经存在的 codepen 项目,我最终得到了这个:

:root {
    --bg: #1a1e24;
    --color: #eee;
    --font: Montserrat, Roboto, Helvetica, Arial, sans-serif;
}

.wrapper {
    padding: 1.5rem 0;
    filter: url('#goo');
}

.bone {
    display: inline-block;
    text-align: center;
    background: var(--color);
    color: var(--bg);
    font-weight: bold;
    padding: 1em 1em 1.03em;
    line-height: 1;
    border-radius: 0.4em;
    position: relative;
    min-width: 8.23em;
    text-decoration: none;
    font-family: var(--font);
    font-size: 1.25rem;
}

.bone:before,
.bone:after {
    width: 2em;
    height: 2em;
    position: absolute;
    content: "";
    display: inline-block;
    background: var(--color);
    border-radius: 50%;
    transition: transform 1s ease;
    transform: scale(0);
    z-index: -1;
    
}

.bone:before {
    top: 50%;
    right: -10%;
}

.bone:after {
    bottom: 50%;
    right: -10%;
}

.bone:hover:before,
.bone:hover:after {
    transform: none;
}

如您所见,我已经能够通过使用::before::after元素在按钮的右侧创建骨骼形状。

但是,现在我想对左侧做同样的事情,我真的不能这样做,因为我已经使用了::beforeand ::after

无论如何要在按钮的左侧做同样的事情吗?

让我们保持简单!您可以spana标签内添加一个,并使用新的伪元素来完成骨骼的左侧部分

您可以使用 CSS 变量调整不同的值以控制最终形状:

.bone {
    --ty:-1em;
    --tx:-1em;
    --s:50px;
    display: inline-block;
    text-align: center;

    font-weight: bold;
    padding: 1em 1em 1.03em;
    margin:2em;
    line-height: 1;
    border-radius: 0.4em;
    position: relative;
    min-width: 8.23em;
    text-decoration: none;
    font-family:  Montserrat, Roboto, Helvetica, Arial, sans-serif;
    font-size: 1.25rem;
    filter: url('#goo');
}

.bone:before {
    content: "";
    position: absolute;
    top:var(--ty);  
    bottom:var(--ty);
    left:0;
    right:0;
    background: 
      radial-gradient(farthest-side,var(--color) 98%,transparent 100%) top    left,

      radial-gradient(farthest-side,var(--color) 98%,transparent 100%) bottom right;
    background-size: 0 0;
