我是靠谱客的博主朴实项链，这篇文章主要介绍css3线性渐变可以实现三角形吗，现在分享给大家，希望可以做个参考。

本教程操作环境：windows7系统、CSS3&&HTML5版、Dell G3电脑。

在css3中，实现三角形有多种方法，其中一种就是利用线性渐变。下面我们就来给大家具体介绍一下。

使用线性渐变 linear-gradient 实现三角形的原理也非常简单，我们实现一个 45° 的渐线性变：

复制代码div {
  width: 100px;
  height: 100px;
  background: linear-gradient(45deg, deeppink, yellowgreen);
}1

div {
  width: 100px;
  height: 100px;
  background: linear-gradient(45deg, deeppink, yellowgreen);
}

让它的颜色从渐变色变为两种固定的颜色：

复制代码div {
  width: 100px;
  height: 100px;
  background: linear-gradient(45deg, deeppink, deeppink 50%, yellowgreen 50%, yellowgreen 100%);

div {

  height: 100px;
  background: linear-gradient(45deg, deeppink, deeppink 50%, yellowgreen 50%, yellowgreen 100%);
}

再让其中一个颜色透明即可：

复制代码div {
  background: linear-gradient(45deg, deeppink, deeppink 50%, transparent 50%, transparent 100%);
}1

div {
  background: linear-gradient(45deg, deeppink, deeppink 50%, transparent 50%, transparent 100%);
}

再通过旋转 rotate 或者 scale，我们也能得到各种角度，不同大小的三角形：

复制代码<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<style>
html,
body {
width: 100%;
height: 100%;
display: flex;
}

div {
width: 100px;
height: 100px;
margin: auto;
}

.rotate {
background: linear-gradient(45deg, deeppink, deeppink 50%, transparent 50%, transparent 1px);
}

.top {
background: linear-gradient(45deg, deeppink, deeppink 50%, transparent 50%, transparent 1px);
transform: rotate(135deg);
}

.left {
background: linear-gradient(45deg, deeppink, deeppink 50%, transparent 50%, transparent 1px);
transform: rotate(45deg);
}

.bottom {
background: linear-gradient(45deg, deeppink, deeppink 50%, transparent 50%, transparent 1px);
transform: rotate(-45deg);
}

.right {
background: linear-gradient(45deg, deeppink, deeppink 50%, transparent 50%, transparent 1px);
transform: rotate(-135deg);
}
