如何将Zig Zag边框添加到框中包含背景图像 [英] How To Add Zig Zag Border to a Box contains background image

问题描述

我已经找到以下完美的CSS代码段，它在此链接。

I already find following perfect CSS snippet which creates zip zag border at this link.

.h-zigzag {
    background:
        linear-gradient(-135deg, #333538 5px, transparent 0) 0 5px,
        linear-gradient(135deg, #333538 5px, #fff 0) 0 5px;
    background-color: #333538;
    background-position: left bottom;
    background-repeat: repeat-x;
    background-size: 10px 10px;
}

正如你可以看到的代码创建一个perfecr zig zag边框，将此边框添加到包含图像的框中：

As you can see the code create a perfecr zig zag border but I need to add this border to a box which contains an image as:

 .h-zigzag {
   background: url(../img/grrenfooter.png) repeat-x top left scroll transparent;
 }

你能帮我混合吗？我已经尝试了几种方法，但是当我混合它们时，图像消失了！

can you please help me to mix them? I already tried several ways but the image disappears when I mix them!

推荐答案

#zigzag {
    width: 600px;
    height: 400px;
    -webkit-mask-image: linear-gradient(0deg, transparent 30px, white 30px), linear-gradient(-135deg, white 15px, transparent 15px), linear-gradient(135deg, white 15px, transparent 15px);
    -webkit-mask-position: left bottom;
    -webkit-mask-repeat: repeat-x;
    -webkit-mask-size: 100% 100%, 30px 30px, 30px 30px;
    background: url("http://placekitten.com/1000/750");
    background-size: cover;
}

body {
    background-image:  repeating-linear-gradient(20deg, lightgreen, lavender 40px);   
}

<div id="zigzag"></div>

锯齿形图案;并且还具有图像的上部也是透明的。当我们使用它作为掩码，它使用透明的背景。

This works by creating an image that has the zigzag pattern ; and also that has the upper part of the image also transparent. When we use that as a mask, it uses the background where it is transparent.

我已将条纹图案设置为正文，以便可以看出锯齿边框真的是透明的

I have set the body with a stripes pattern so that it can be seen that the zig zag border is really transparent
