问题描述
如下图所示,我正在尝试使div的底部和顶部弯曲或成三角形,但我不知道该怎么做.我只是尝试了几次,但是无法达到目的.那么如何在psuedo之前使用after呢?伪装无关紧要,但我想知道怎么做?
As you can see in the image below, I am trying to warp or triangle my div from bottom and top, but I have no idea how to do it. I just tried a couple of times to do it, but I couldn't achieve the result. So how can I make it using after,before psuedo? It doesn't matter make with psuedo, but I wonder that how to do it?
这是我的代码:
body{
background:lightblue;;
}
.block{
background-image: linear-gradient(to right, #314b56, #283b44, #1f2c32, #161e21, #0a0f11);
border: 1px solid #fff;
width: 300px;
height: 150px;
margin: 30px;
}
<div class="block"></div>
推荐答案
使用变换和透视图的想法,您将获得边界,边界半径以及渐变:
An idea using transformation and perspective where you will have the border, border-radius also the gradient:
body {
background: lightblue;
}
.block {
overflow: hidden;
width: 300px;
height: 200px;
margin: 20px;
position: relative;
z-index:0;
}
.block::before,
.block::after {
content: "";
position: absolute;
z-index:-1;
border: 1px solid #fff;
top: 0;
bottom: 0;
width: 50%;
background-image: linear-gradient(to right, #314b56, #283b44, #1f2c32, #161e21, #0a0f11);
background-size: 200% 100%;
}
.block::before {
left: 0;
border-right: 0;
border-radius: 15px 0 0 15px;
transform-origin: right;
transform: perspective(100px) rotateY(-5deg);
}
.block::after {
right: 0;
border-left: 0;
border-radius: 0 15px 15px 0;
transform-origin: left;
transform: perspective(100px) rotateY(5deg);
background-position: right;
}
<div class="block"></div>
您还可以添加阴影并轻松更改渐变:
You can also add the shadow and easily change the gradient:
body {
background: lightblue;
}
.block {
overflow: hidden;
width: 300px;
height: 200px;
margin: 20px;
position: relative;
z-index:0;
filter:drop-shadow(0 0 5px #000);
}
.block::before,
.block::after {
content: "";
position: absolute;
z-index:-1;
border: 1px solid #fff;
top: 0;
bottom: 0;
width: 50%;
background-image: linear-gradient(35deg, blue, red);
background-size: 200% 100%;
}
.block::before {
left: 0;
border-right: 0;
border-radius: 15px 0 0 15px;
transform-origin: right;
transform: perspective(100px) rotateY(-5deg);
}
.block::after {
right: 0;
border-left: 0;
border-radius: 0 15px 15px 0;
transform-origin: left;
transform: perspective(100px) rotateY(5deg);
background-position: right;
}
<div class="block"></div>
