问题描述
我正在尝试使用伪元素为我的剪辑路径创建边框.我已经尝试过更改它们的位置,而我的伪元素仍然停留在其顶部.我该如何更改?您可以在这里看到我的代码.
I'm trying to create a border to my clip path using pseudo-elements. I have already tried to change positioning in them and my pseudoelement still stay on top of it. How can I change this? You can see my code in here.
#shield {
z-index: 1;
background-color: red;
box-shadow: 1px 1px 1px black;
background-image: url("https://upload.wikimedia.org/wikipedia/commons/9/91/Bras%C3%A3o_Porto_Feliz.png");
background-size: 50%;
background-repeat: no-repeat;
background-position: center;
background-blend-mode: multiply;
display: inline-block;
height: 120px;
width: 200px;
-webkit-clip-path: polygon(100% 0, 100% 75%, 50% 100%, 0% 75%, 0 0);
clip-path: polygon(100% 0, 100% 75%, 50% 100%, 0% 75%, 0 0);
}
#logo {
width: 100px;
height: 100px;
}
#shield::before {
top: 0;
left: 0;
transform: scale(1.2);
content:"";
display: block;
width: 100%;
height: 100%;
background-color: black;
position: absolute;
z-index: -1;
}
<div class="navbar-brand navbar-brand-centered" id="shield">
</div>
要查看我想要的内容,只需删除:: before元素
To see what I wanted to be in top of things, just delete the ::before element

先谢谢您了:)
推荐答案
只需翻转一下即可.在::: after中使用背景图片,并在实际div中使用黑色.
Just flip it around. Use your background image in your ::after and your black color for the actual div.
#shield {
z-index: 1;
background-color: black;
box-shadow: 1px 1px 1px black;
position: relative;
display: inline-block;
height: 120px;
width: 200px;
-webkit-clip-path: polygon(100% 0, 100% 75%, 50% 100%, 0% 75%, 0 0);
clip-path: polygon(100% 0, 100% 75%, 50% 100%, 0% 75%, 0 0);
}
#logo {
width: 100px;
height: 100px;
}
#shield::before {
top: 0;
left: 0;
transform: scale(1.2);
content:"";
display: block;
width: 100%;
height: 100%;
background-image: url("https://upload.wikimedia.org/wikipedia/commons/9/91/Bras%C3%A3o_Porto_Feliz.png");
background-repeat: no-repeat;
background-position: center;
background-blend-mode: multiply;
position: absolute;
z-index: 1;
background-size: 50%;
}
<div id="shield"></div>
