我的图片标签尺寸固定且很小（150 * 150），因为我的svg尺寸可能会有所不同（目前为1366 * 768）。
在所有其他浏览器中，svg图像缩放为图像标签尺寸。
在IE图像中本身没有显示出来。
如果我增加图片标签尺寸，则显示1000 * 1000。
我应该做些什么来在IE中像其他bowsers一样显示图像？
答案 0 :(得分：3)
您应该将viewBox="0 0 [width] [height]"添加到<svg />根元素以使其缩放。
这是你viewBox="0 0 1366 768"的小提琴：

顺便说一下，您还可以查看preserveAspectRatio属性，该属性允许您控制图像的缩放方式。
