是否可以用css渐变做一条曲线?

问题描述

我从一个客户那里得到了这个设计，按钮中有两层渐变.棘手的是，其中一层具有弯曲的边缘.我模拟了按钮，希望您能明白我在说什么.

I have this design from a client with two layers of gradients in a button. The tricky thing is, one of the layers has a curved edge. I've mocked up the button so you have a sense of what I'm saying, hopefully.

我设法做的是一条直边(见代码片段，色差不重要，只需要曲线).有没有人以前做过这个?还是必须是背景图片?谢谢！

What I managed to do is a straight edge (see code snippet, color difference is not important, just need the curve). Does anyone have done this before? Or does it have to be a background image? Thanks!

附言我也想过在伪元素上使用径向渐变并绝对定位它，但无法获得像线性渐变一样的精确直边.

P.S. I also thought about using radial gradient on a pseudo element and absolute position it, but couldn't get the exact straight edge look like the linear gradient.

a {
  background-image: linear-gradient(-155deg,rgba(74,148,214,.4) 45%,rgba(255,255,255,.08) 15%),linear-gradient(258deg,rgba(87,238,255,.1),rgba(77,108,211,.2));
  background-color: rgba(74,148,214,.9);
  color: #fff;
  width: 200px;
  height: 40px;
  border-radius: 10px;
  margin-top: 50px;
  display: block;
  text-align: center;
  line-height: 40px;
}

<a>
  Some button
</a>

推荐答案

您可以使用 radial-gradient 而不是线性:

You can get pretty close by using a radial-gradient instead of linear:

a {

background-image:
  radial-gradient(ellipse farthest-corner at 0 140%, #3c84cc 0%, #316dc2 70%, #4e95d3 70%);
  color: white;
  width: 200px;
  height: 50px;
  border-radius: 10px;
  margin-top: 50px;
  display: block;
  text-align: center;
  line-height: 50px;
}

<a>
  Some button
</a>
