有关如何在photoshop中执行此操作的教程here:
我只想用CSS做这件事。我能越接近fiddle。
hr.fancy-line {
border: 0;
height: 1px;
background-image: -webkit-linear-gradient(left, rgba(0,0,0,0), rgba(215,215,215,0.75), rgba(0,0,0,0));
background-image: -moz-linear-gradient(left, rgba(0,0,0,0), rgba(215,215,215,0.75), rgba(0,0,0,0));
background-image: -ms-linear-gradient(left, rgba(0,0,0,0), rgba(215,215,215,0.75), rgba(0,0,0,0));
background-image: -o-linear-gradient(left, rgba(0,0,0,0), rgba(215,215,215,0.75), rgba(0,0,0,0));
box-shadow: 0px -2px 4px rgba(136,136,136,0.75);
}
<hr class="fancy-line"></hr>
对阴影做渐变似乎非常困难。 我有什么想法可以改善这个吗?

我会将radial-gradient
用于伪元素而不是box-shadow
,因为它会向边缘逐渐变细。
将radial-gradient
放在<hr>
上方,使其缩小一半。然后在<hr>
正下方放置另一个psuedo元素,其颜色与背景相同,高度足以覆盖渐变的其余部分。

hr.fancy-line {
border: 0;
height: 1px;
}
hr.fancy-line:before {
top: -0.5em;
height: 1em;
}
hr.fancy-line:after {
content:'';
height: 0.5em;
top: 1px;
}
hr.fancy-line:before, hr.fancy-line:after {
content: '';
position: absolute;
width: 100%;
}
hr.fancy-line, hr.fancy-line:before {
background: radial-gradient(ellipse at center, rgba(0,0,0,0.1) 0%,rgba(0,0,0,0) 75%);
}
body, hr.fancy-line:after {
background: #f4f4f4;
}

请查看https://codepen.io/ibrahimjabbari/pen/ozinB。 该网站提供18种风格的水平线条。有些看起来很棒。
以下是一个例子。
hr.style17 {
border-top: 1px solid #8c8b8b;
text-align: center;
}
hr.style17:after {
content: '§';
display: inline-block;
position: relative;
top: -14px;
padding: 0 10px;
background: #f0f0f0;
color: #8c8b8b;
font-size: 18px;
-webkit-transform: rotate(60deg);
-moz-transform: rotate(60deg);
transform: rotate(60deg);
}

以下是实现此目的的最简单形式:
hr{
border: 0;
height: 1px;
background-image: -webkit-linear-gradient(left, #f0f0f0, #8c8b8b, #f0f0f0);
background-image: -moz-linear-gradient(left, #f0f0f0, #8c8b8b, #f0f0f0);
background-image: -ms-linear-gradient(left, #f0f0f0, #8c8b8b, #f0f0f0);
background-image: -o-linear-gradient(left, #f0f0f0, #8c8b8b, #f0f0f0);
}
