嗨,我正在尝试做以下事情:
它们的三角形的高度应为容器的高度的40%,宽度应为50%,因此它们在中间相遇。
我一直在尝试做类似的事情..但到目前为止没有成功..
环顾四周,我发现到目前为止我什么也无法使用。
我的代码:
div {
height: 373px;
width: 0px;
margin: 26px;
display: inline-block;
}
.left {
border-bottom: 100px solid #ff0;
border-left: 320px solid transparent;
}
.right {
border-bottom: 100px solid #f00;
border-right: 320px solid transparent;
}
header {
border: 2px solid black;
width: 50%;
height: 500px;
}
<header>
<div class="right"></div>
<div class="left"></div>
</header>
希望有人比我聪明,看看我应该从这里去...

使用如下背景色:
.box {
height:300px;
background:
/* Right bottom triangle*/
linear-gradient(to bottom right,transparent 49.5%,blue 50%) bottom right,
/* left bottom triangle*/
linear-gradient(to bottom left ,transparent 49.5%,red 50%) bottom left ,
yellow;
background-size:50% 40%; /* Width height*/
background-repeat:no-repeat;
}
<div class="box">
</div>

关于伪元素的另一种想法(可以替换为通用元素),以防您拥有其他元素。
.box {
height: 300px;
background: yellow;
position: relative
}
.box:before,
.box:after {
content: "";
position: absolute;
height: 40%;
width: 50%;
bottom: 0;
}
.box:before {
left: 0;
background: linear-gradient(to bottom left, transparent 49.5%, red 50%);
}
.box:after {
right: 0;
background: linear-gradient(to bottom right, transparent 49.5%, blue 50%);
}
<div class="box">
</div>

由于需要百分比值,因此可以使用clip-path
。请注意,某些浏览器https://caniuse.com/#feat=css-clip-path可能不完全支持它,对于某些浏览器,您可能需要前缀(例如-webkit-clip-path
)
.wrap {
height: 200px;
width: 100%;
position: relative;
background: #333;
}
.triangle {
background: red;
clip-path: polygon(0 40%, 0% 100%, 100% 100%);
position: absolute;
left: 0;
bottom: 0;
top: 0;
width: 50%;
}
.triangle.tr-right {
left: auto;
right: 0;
clip-path: polygon(100% 40%, 0% 100%, 100% 100%);
}
<div class="wrap">
<div class="triangle tr-left"></div>
<div class="triangle tr-right"></div>
</div>
