Stretch SVG background image?

问题

It's easy to stretch a png background image:

.stretched-logo-bg {
    background: url("../img/curve.png") center center no-repeat;
    background-size: 100% 100%;
}

this won't work with an SVG background though

.stretched-logo-bg {
    background: url("../img/curve.svg") center center no-repeat;
    background-size: 100% 100%;
}

it won't get stretched, it will maintain its aspect ratio and just center.

At least in Chrome 52

If you need to override the preserveAspectRatio of the SVG you are displaying you can use an SVG fragment identifier to do that e.g.

.stretched-logo-bg {
    background: url("../img/curve.svg#svgView(preserveAspectRatio(none))") center center no-repeat;
    background-size: 100% 100%;
}

I don't believe that you can make a SVG to distort like you can with PNGs.

However, if you are mostly supporting modern browsers, you can add preserveAspectRatio="none" attribute to the SVG tag.

For example:

<svg version="1.1" preserveAspectRatio="none" .. etc`
