我想在网站上的一些元素上添加标签,并设计一个标签,底部是倒V形切口的旗帜。
到目前为止,我有这个:
<div class="css-shapes"></div>
.css-shapes{
border-left: 99px solid #f00fff;
border-right: 99px solid #f00fff;
border-bottom: 39px solid transparent;
}

然而,我需要背景是白色的并且在紫色和1px的这个形状周围边界。我试图在这个内部装入相同形状的白色,但是一切都变得混乱而且没有像预期的那样。
也许这是一种错误的方法,但我希望最终得到的标签看起来像这样:

使用CSS:
您可以在伪元素上使用CSS transforms来创建底部带有透明倒三角形的背景:
body{background:url('http://lorempixel.com/image_output/food-q-c-640-480-1.jpg');background-size:cover;}
p{
position: relative;
width: 150px; height: 150px;
overflow: hidden;
border-top:3px solid #EF0EFE;
}
p:before, p:after{
content: '';
position: absolute;
top: -3px;
height: 100%; width: 50%;
z-index: -1;
border:2px solid #EF0EFE;
box-sizing:border-box;
}
p:before{
left: 0;
transform-origin: 0 0;
transform: skewY(-20deg);
border-width:0 0 4px 3px;
}
p:after{
right: 0;
transform-origin: 100% 0;
transform: skewY(20deg);
border-width:0 3px 4px 0;
}
&#13;
<p>Some text ... </p>
&#13;
请注意,您需要在transform
和transform-origin
属性上添加供应商前缀,以最大限度地提高浏览器支持。有关详细信息,请参阅canIuse。
使用SVG
另一种方法是使用带有多边形元素的inline SVG:
body{background: url('http://lorempixel.com/image_output/food-q-c-640-480-1.jpg');background-size: cover;}
div{position: relative;width: 100px; height: 150px;}
svg{position: absolute;width: 100%;height: 100%;z-index: -1;}
&#13;
<div>
<svg viewbox="-1.5 -1.5 103 153">
<polygon points="100 0, 100 100, 50 85, 0 100, 0 0" fill="transparent" stroke-width="3" stroke="#ef0efe"/>
</svg>
<p>Some text ... </p>
</div>

使用pseudo-elements和transform旋转创建如下所示的轮廓横幅的方法略有不同:
position: absolute
个伪元素:before
和:after
创建:
overflow: hidden
切断多余的部分以形成我们的横幅:
box-shadow
创建轮廓,并通过拉动/推动x轴46px防止两个角度重叠 - box-shadow: 46px 0 0 3px #000
div {
height: 100px;
width: 100px;
margin: 100px auto;
position: relative;
overflow: hidden;
border: solid 3px #000;
border-bottom: none;
text-align: center;
}
div:before,
div:after {
content: '';
display: block;
height: 100%;
width: 200%;
transform: rotate(20deg);
box-shadow: 46px 0 0 3px #000;
position: absolute;
top: 1px;
right: -120%;
}
div:after {
transform: rotate(-20deg);
left: -120%;
box-shadow: -46px 0 0 3px #000;
}

<div>Text</div>

我的方法使用偏斜元素,并允许您快速定位它们。
div {
height: 100px;
width: 100px;
position: relative;
border-left: 10px solid tomato;
border-top: 10px solid tomato;
border-right: 10px solid tomato;
text-align: center;
line-height: 100px;
font-size: 30px;
}
div:before {
content: "";
position: absolute;
height: 50%;
width: 50%;
left: -10px; /*width of border*/
bottom: -30px;
z-index: -2;
-webkit-transform: skewY(-20deg);
transform: skewY(-20deg);
border-bottom: 10px solid tomato;
border-left: 10px solid tomato;
}
div:after {
content: "";
position: absolute;
height: 50%;
width: 50%;
right: -10px; /*width of border*/
bottom: -30px;
z-index: -2;
-webkit-transform: skewY(20deg);
transform: skewY(20deg);
border-bottom: 10px solid tomato;
border-right: 10px solid tomato;
}
div:hover, div:hover:before, div:hover:after{

一种更好的解决方案,将文本轻松放置在中间,底部使用矩形背景,底部使用三角形。
