I have had to do similar, but in SVG. Back in the days before flexbox I had a project that needed to print colour reports in IE7+. Browser print removes background colours except for web graphics, so SVG can be used as a workaround. However, IE supported only it's own weird fork of SVG called VML. This was how I ended up writing flexbox like layout code for SVG with a VML bridge. Was a good project as a junior developer.
