IE11 SVG background images not displaying correctly
The Problem
There is an issue with IE11 when rendering some types of SVG files the styles are embedded as a <style></style> element inside the SVG file.
Because IE11 uses a different rendering engine for CSS images and HTML images the images differ from when including the SVG file inside compared to when using the <img> tag.
E.g.
<img src="/images/badge.svg" width="32" height="32"/>
vs
.badge{ background-image: url('/images/badge.svg'); }
The Solution
In total there are four ways of exporting an SVG from Illustrator or other tools:
Presentation Attributes
Style Attributes
Style Attributes (Entity Reference)
Style Elements (this does not work in IE)
In order to export the SVG file correctly follow these steps (Adobe Illustrator CC 2017).
