由两个直角三角形组成的页脚 [英] Footer consisting of two right triangles

问题描述

我正在建立一个网站，我希望页脚看起来像这样: https://imgur.com/a/JuHHHkM

I'm making a website and I want the footer to look like this: https://imgur.com/a/JuHHHkM

基本上是彼此重叠的两个三角形.我试图制作这样的三角形:

It's basically two triangles on top of each other. I've tried to make triangles like this:

#triangle-bottomleft {
width: 0;
height: 0;
border-bottom: 100px solid red;
border-right: 100px solid transparent;
}    

但是因为宽度取决于您在右边框中放置的像素数，所以我不能使用宽度:100％.

But because the width depends on how many pixels you put in the border-right, I cannot use width: 100%.

还有其他选择吗? 在此先感谢

Any Alternatives? Thanks in Advance

推荐答案

您可以使用渐变轻松实现此目的:

You can easily achieve this with gradients:

.footer {
  height:100px;
  background:
   linear-gradient(to bottom right,transparent 49.5%,blue 50%),
   linear-gradient(to bottom left,transparent 49.5%,green 50%);
}

<div class="footer">
</div>

如果您不希望三角形为全角，也可以调整大小:

You can also adjust the size if you don't want the triangle to be full width:

.footer {
  height:100px;
  background:
   linear-gradient(to bottom right,transparent 49.5%,blue 50%) right/80% 100% no-repeat,
   linear-gradient(to bottom left,transparent 49.5%,green 50%) left/80% 100% no-repeat;
}

<div class="footer">
</div>
