虚线顶部和底部边框比文本短
Dotted top and bottom border shorter than text
我想实现如下图所示的顶部和底部边框,我该如何使用 CSS 技巧实现?
挑战是我不想要带边框的整个宽度,它也应该是响应式的。
移动版图像是 http://i.imgur.com/XZTW28N.jpg,它应该也适用于桌面和移动浏览器。
我尝试使用 %width 边框,但它不起作用。
我写了下面的代码,但这对我来说不是 100% 完美的答案。
HTML:
<h1>How it Works</h1
CSS:
h1:before, h1:after {
content: "";
height: 1px;
background: linear-gradient(to right, rgba(0,0,0,0) 0%,rgba(147,147,147,1) 50%,rgba(0,0,0,0) 100%);
display: block;
margin-bottom: 10px;
margin-top: 10px;
}
我对你的CSS做了一些修改:
h1{
text-align: center;
font-size: 70px;
}
h1:before, h1:after{
position: relative;
content: "";
width: 30%;
left: 35%;
display: block;
margin-bottom: 10px;
margin-top: 10px;
border-bottom: 5px dotted yellow;
}
编辑:
如果你想要一个固定的 width
你可以添加:
h1:before, h1:after{
width: 150px; /* You can change this value */
left: 50%;
transform: translateX(-50%);
}
这是另一种使用 radial-gradient
背景图像在顶部和底部生成点的方法。输出是响应式的,没有。顶部和底部的点数由宽度决定(例如,width: 108px
产生 9 个点,因为 background-size
在 x 轴上是 12px
)。
与其他方法相比,这种方法的优势在于可以更好地控制点的大小以及点之间的 space。缺点是 browser support for radial-gradient
与虚线边框方法相比较低 (IE10+)。
h1 {
position: relative;
text-align: center;
font-size: 48px;
line-height: 1em;
padding: 0.625em;
font-family: Calibri;
font-weight: 100;
}
h1:after {
position: absolute;
content: '';
width: 108px; /* multiples of background-size in X-axis */
height: 100%;
top: 0px;
left: calc(50% - 50px);
background: radial-gradient(circle at 50% 50%, rgb(250, 189, 38) 30%, transparent 50%), radial-gradient(circle at 50% 50%, rgb(250, 189, 38) 30%, transparent 50%);
background-size: 12px 6px;
background-repeat: repeat-x;
background-position: 50% 0.125em, 50% 2em;
}
/* Just for demo */

<h1>How it works</h1>
<h1>How it works with long text</h1>
带大点的截图:
要使点变小,只需降低径向渐变的色标百分比即可。百分比越小,圆点越小。

小圆点截图:
您也可以使用 box-shadows
来实现此目的,首先在顶部创建一个 after
伪元素,在底部创建一个 before
伪元素,然后给出 box-shadows

position:relative;
