我目前有以下"扁长阴影" (我已经删除了3/4的代码,以免崩溃stackoverflow - 在我的文本编辑器中,每个阴影都有自己的行,它来自大约600行代码),我根据{{3 }} Matt Lambert's。

我想在我的网站中加入这个内容,但我对它占用的代码长度感到沮丧(在这种情况下,我不能使用图形)。
我研究过编写较少代码的方法,但还没有找到一种简单的CSS方式 - AKA no SASS等。
tutorial我发现的一件事 - 不太有希望:
上面的示例几乎是使用纯CSS实现它的唯一方法,虽然看起来确实非常疯狂 - 它会让你使用转换等来调整这些文本阴影。 - @Lost Left Stack
如果有更紧凑的方法,我想再次询问stackoverflow社区。 p>

你可以使用2个带偏斜的伪来模拟相同的阴影
div {
min-height: 64px;
width: 64px;
text-align: center;
background-color: cyan;
border: 1px solid blue;
position: relative;
}
div:before, div:after {
content: "";
position: absolute;
top: -1px; /* compensate border in the root element */
left: -1px;
right: -1px;
bottom: -1px;
z-index: -1;
transform-origin: right bottom;
}
div:before {
transform: skewX(45deg);
box-shadow: 1px 60px 0px 0px gray, 1px 120px 0px 0px lightgray; /* 1px in x direction to avoid small gap between shadows */
}
div:after {
transform: skewY(45deg);
box-shadow: 60px 0px gray, 120px 0px lightgray;
}
&#13;
<div>
wow that's a lot of CSS!
</div>

这种方法的一个优点是你可以轻松地调整阴影的角度
body {
background-color: #ddd;
}
div {
min-height: 64px;
width: 64px;
text-align: center;
background-color: cyan;
border: 1px solid blue;
position: relative;
}
div:before, div:after {
content: "";
position: absolute;
top: -1px; /* compensate border in the root element */
left: -1px;
right: -1px;
bottom: -1px;
z-index: -1;
transform-origin: right bottom;
}
div:before {
transform: skewX(60deg);
box-shadow: 1px 34px 0px 0px gray; /* 1px in x direction to avoid small gap between shadows */
}
div:after {
transform: skewY(30deg);
box-shadow: 60px 0px gray;
}
&#13;
<div>
wow that's a lot of CSS!
</div>
&#13;
要实现更长的阴影,可以增加伪尺寸:
div {
min-height: 64px;
width: 64px;
text-align: center;
background-color: cyan;
border: 1px solid blue;
position: relative;
}
div:before, div:after {
content: "";
position: absolute;
right: -1px;
bottom: -1px;
z-index: -1;
transform-origin: right bottom;
}
div:before {
height: 200px; /* increased height */
left: -1px;
transform: skewX(45deg);
box-shadow: 1px 200px 0px 0px gray; /* 1px in x direction to avoid small gap between shadows */
}
div:after {
width: 200px; /* increased width */
top: -1px;
transform: skewY(45deg);
box-shadow: 200px 0px gray;
}
&#13;
<div>
wow that's a lot of CSS!

如果您正在使用SASS或SCSS,则会剪切元素及其box-shadow属性,如下所示:
div {
box-shadow: /* your very long value */;
}
然后将其粘贴到另一个SASS / SCSS文件中。例如,您将其命名为boxShadow.scss
。之后,将其导入主SASS / SCSS文件,如下所示:@import 'boxShadow'
。通过这样做,您可以为主SASS / SCSS文件节省大量空间。
