我想使用动态文本作为标签中某些元素的背景.因此,我可以使用图像(动态文本).我怎么用CSS或JavaScript做到这一点？

如何在SVG的文本的背景图像？
body {
background-image:url("data:image/svg+xml;utf8,<svg xmlns='http://www.w3.org/2000/svg' version='1.1' height='50px' width='120px'><text x='0' y='15' fill='red' font-size='20'>I love SVG!</text></svg>");
}<p>I hate SVG!</p><p>I hate SVG!</p><p>I hate SVG!</p><p>I hate SVG!</p>
<p>I hate SVG!</p><p>I hate SVG!</p><p>I hate SVG!</p><p>I hate SVG!</p>CSS这样你就可以更好地理解的缩进版本(这并没有工作,你需要使用单排SVG):
body {
background-image:url("data:image/svg+xml;utf8,
<svg xmlns='http://www.w3.org/2000/svg' version='1.1'
height='50px' width='120px'>
<text x='0' y='15' fill='red' font-size='20'>I love SVG!</text>
</svg>");
}
不确定它是多么便携(适用于Firefox 31和Chrome 36),它在技术上是一个图像......但源是内联和纯文本,它无限扩展.
如果你对base64进行编码,@ senectus发现它在IE上工作得更好:https://stackoverflow.com/a/25593531/895245

您可以在相对定位元素内部放置一个绝对定位的元素:
<div id="container">
<div id="background">
Text to have as background
</div>
Normal contents
</div>
然后是CSS:
#container {
position: relative;
}
#background {
position: absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
z-index: -1;
overflow: hidden;
}
这是一个例子.

只有CSS使用:before或:after伪元素可能(但非常hackish):
.bgtext {
position: relative;
}
.bgtext:after {
content: "Background text";
position: absolute;
top: 0;
left: 0;
z-index: -1;
}这似乎有效,但你可能需要稍微调整一下.另请注意,它不适用于IE6,因为它不支持:after.

Ciro关于包含文本的SVG数据URI背景的解决方案非常聪明.
但是,如果只是将普通SVG源添加到数据URI,它将无法在IE中运行.
为了解决这个问题并使其在IE9及更高版本中运行,请将SVG编码为base64.这是一个很棒的工具.
所以这:
background:url('data:image/svg+xml;utf8,<svg xmlns="http://www.w3.org/2000/svg"><text x="5%" y="5%" font-size="30" fill="red">I love SVG!</text></svg>');
变成这样:
background:url('data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjx0ZXh0IHg9IjUlIiB5PSI1JSIgZm9udC1zaXplPSIzMCIgZmlsbD0icmVkIj5JIGxvdmUgU1ZHITwvdGV4dD48L3N2Zz4=');
经过测试,它适用于IE9-10-11,WebKit(Chrome 37,Opera 23)和Gecko(Firefox 31).

您可以使用反斜杠来破坏内嵌的svg代码 "\"
在Chrome 54和Firefox 50中使用以下代码进行了测试
body {
background: transparent;
background-attachment:fixed;
background-image: url(
"data:image/svg+xml;utf8,<svg xmlns='http://www.w3.org/2000/svg' version='1.1' width='170px' height='50px'> \
<rect x='0' y='0' width='170' height='50' style='stroke:white; fill:gray; stroke-opacity: 0.3; stroke-width: 3px; fill-opacity: 0.7; stroke-dasharray: 10 5; stroke-linecap=round; '/> \
<text x='85' y='30' style='fill:lightBlue; text-anchor: middle' font-size='16' transform='rotate(10,85,25)'>I love SVG!</text></svg>");
}
我什至测试过
background-image: url("\
data:image/svg+xml;utf8, \
<svg xmlns='http://www.w3.org/2000/svg' version='1.1' width='170px' height='50px'> \
<rect x='0' y='0' width='170' height='50'\
style='stroke:white; stroke-width: 3px; stroke-opacity: 0.3; \
stroke-dasharray: 10 5; stroke-linecap=round; \
fill:gray; fill-opacity: 0.7; '/> \
<text x='85' y='30' \
style='fill:lightBlue; text-anchor: middle' font-size='16' \
transform='rotate(10,85,25)'> \
I love SVG! \
</text> \
</svg>\
");
并且有效（至少在Chrome 54和Firefox 50 ==>保证在NWjs和Electron中使用）
我希望这可以帮助你
