我已尝试过我在网上找到的常用解决方案,但无法获得 要出现的背景图片。
在第一个标题中,SVG图像似乎比其viewBox
推出的容器要远得多。在第2个标题中,背景图像根本不显示。 (SVG代码相同)
HTML:
header {
margin: 1rem auto 0 auto;
border: 1px solid red;
}
.container {
border: 2px dotted orange;
}
.container svg {
border: 1px dashed blue;
width: 100%;
height: 100%;
}
#inline-svg {
border: 2px dashed pink;
}
#header1 {}
#header2 {
background-image: url("data:image/svg+xml;utf8,<svg xmlns='http://www.w3.org/2000/svg' id='background-svg' width='400px' height='200px' viewBox='0 0 400px 200px'>
<ellipse cx='200' cy='100' rx='200' ry='100' fill='green' /> </svg>");
background-size: auto auto;
}
#background-svg {
border: 3px solid black;
}
&#13;
<header id="header1" class="masthead">
<div id="1st-container" class="container">
<svg xmlns='http://www.w3.org/2000/svg' id='inline-svg' width='200px' height='100px' viewBox='0 0 200px 200px'>
<ellipse cx='200' cy='100' rx='200' ry='100' fill='green' />
</svg>
</div>
</header>
<header id="header2" class="masthead">
<div id="2nd-container" class="container">
hello
</div>
</header>

当你在url中添加svg代码时请不要破坏它,否则它无法正常工作。
header {
margin: 1rem auto 0 auto;
border: 1px solid red;
}
.container {
border: 2px dotted orange;
}
.container svg {
border: 1px dashed blue;
width: 100%;
height: 100%;
}
#inline-svg {
border: 2px dashed pink;
}
#header1 {}
#header2 {
background-image: url("data:image/svg+xml;utf8,<svg xmlns='http://www.w3.org/2000/svg' id='background-svg' width='400px' height='200px' viewBox='0 0 400px 200px'><ellipse cx='200' cy='100' rx='200' ry='100' fill='green' /> </svg>");
background-size: auto auto;
}
#background-svg {
border: 3px solid black;
}
<header id="header1" class="masthead">
<div id="1st-container" class="container">
<svg xmlns='http://www.w3.org/2000/svg' id='inline-svg' width='200px' height='100px' viewBox='0 0 200px 200px'>
<ellipse cx='200' cy='100' rx='200' ry='100' fill='green' />
</svg>
</div>
</header>
<header id="header2" class="masthead">
<div id="2nd-container" class="container">
hello
</div>
</header>
