我想使用::before在一些选定的元素之前放置SVG图像:
#mydiv::before {
content: '<svg ... code here</svg>';
display: block;
width: 22px;
height: 10px;
margin: 10px 5px 0 10px;
}
上面的代码只显示明文。 我检查了规范，似乎有一些限制什么内容可以。CSS内容属性解决方案是可取的。
当前回答
.myDiv {
display: flex;
align-items: center;
}
.myDiv:before {
display: inline-block;
content: url(./dog.svg);
margin-right: 15px;
width: 10px;
}

是的，你可以!刚刚测试了这个，它工作得很好，这是了不起的!
#test::before {
content: url(path/to/your.svg);
width: 200px;
height: 200px;
}
或者如果你喜欢把SVG直接放在CSS中:
#测试::{之前 content: url("data:image/svg+xml，%3Csvg xmlns='http://www.w3.org/2000/svg'%3E%3Ccircle cx='100' cy='50' r='40' stroke='black' stroke-width='2' fill='red'/%3E%3Cpolyline points='20,20 40,25 60,40 80,120 120,140 200,180' style='fill:none;stroke:black;stroke-width:3'/%3E%3C/svg%3E "); 宽度:200 px; 身高:200 px; ｝ < div id = "测试" > < / div >
SVG URL编码器来格式化您自己的SVG，如下所示。
你可以使用url() CSS函数。
#mydiv::before {
content: url("data:image/svg+xml; utf8, <svg ... code here</svg>");
display: block;
width: 22px;
height: 10px;
margin: 10px 5px 0 10px;
}
确保您的SVG不包含任何#符号。使用像这样的编码器。
您可以添加SVG作为空的:after或:before的背景图像。
给你:
.anchor:before {
display: block;
content: ' ';
background-image: url('../images/anchor.svg');
background-size: 28px 28px;
height: 28px;
width: 28px;
}
虽然这是很多年前的事了，但我还是想分享一下。
上面的答案是正确的，您可以直接将编码后的svg字符串附加到css content属性中。对于那些与URL有任何问题的人来说，可能是由于空格和字符无效，在这种情况下，将您解码的SVG代码粘贴到: https://mothereff.in/url
使用编码后的SVG URL应该可以正常工作。 错误和正确的例子:
#incorrect::before {
content: url(
data:image/svg + xml,
<svgid="Layer_1"data-name="Layer 1"xmlns="http://www.w3.org/2000/svg"viewBox="0 0 15.37 188.41"><defs><style>.cls-1{fill:#aeadad;}</style></defs><circleclass="cls-1"cx="7.69"cy="7.69"r="7.69"/><rectclass="cls-1"x="6.69"y="27.72"width="2"height="160.69"/></svg>
);
}
#correct::before {
content: url(data:image/svg+xml,%0A%3Csvg%20id%3D%22Layer%5f1%22%20data-name%3D%22Layer%201%22%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20viewBox%3D%220%200%2015.37%20188.41%22%3E%3Cdefs%3E%3Cstyle%3E.cls-1%7Bfill%3A%23aeadad%3B%7D%3C%2Fstyle%3E%3C%2Fdefs%3E%3Ccircle%20class%3D%22cls-1%22%20cx%3D%227.69%22%20cy%3D%227.69%22%20r%3D%227.69%22%2F%3E%3Crect%20class%3D%22cls-1%22%20x%3D%226.69%22%20y%3D%2227.72%22%20width%3D%222%22%20height%3D%22160.69%22%2F%3E%3C%2Fsvg%3E%0A);
