关于SVG
以前前端IE6时代做按钮， 图标背景图用gif, png， 后来主流png, 现在各种流体结构，高分屏的需求， svg大行其道， 无论是体积还是灵活性还是品质都远胜png。
之前自己也总结了一下使用svg的各种方法吧：
1.直接使用<img> + .svg 文件， 这种跟使用png没区别， 不能改变颜色， IE11还不能改变<img> 里面图片的高和宽， 也就没有任何意义了通常.
适用：Chrome, Firefox, Edge
<img class="svg-test-img" src="./i/icon-rearrange.svg" alt="">IE11的显示
2.用<img> + .svg 文件的代码， 这种形式不能用于IE, 会显示一个X的图片
适用：Chrome, Firefox， Edge

F.用mask 改变svg 图片颜色, IE/EDGE不显示,
Chrome 需要添加-webkit-前缀
这种方法不能改变宽高， 意义不大， 一定要在<svg>内改变宽高
适用：NA
<span class="svg-b svg-test-bgmarsk"></span>.svg-test-bgmarsk { -webkit-mask: url('../i/icon-rearrange.svg') no-repeat 50% 50%; // must for chrome mask: url('../i/icon-rearrange.svg') no-repeat 50% 50%; //work for firefox }Chrome/Firefox 显示：
IE/Edge显示：
总结：
用base64的方法最好，这种就需要你先改好颜色在转换
如果只需要支持Chrome/Firefox，可以用 url('data:image/svg+xml,<svg> ...</svg>) 然后在里面的fill="rgb(0, 0, 0)"修改颜色
如果需要支持现在所有主流浏览器，用URL decode， 找到rgb(147%2C%20147%2C%20147) 修改颜色
我的环境：
Win10
Chrome: Version 63.0.3239.132 (Official Build) (64-bit)
IE11: 11.192.16299.0
Edge: Microsoft Edge 41.16299.15.0
Firefox: 57.0.4 (64-bit)
没有在mac上测试safari, 没有测试手机端。
