How to make fallbacks?

Question

css

Hello! In my project, I use flexbox for everything from document structure to buttons and blocks. Blog readers and site visitors began to complain that IE 9 was catching bugs. Why they catch them is understandable. Another thing that is not clear is how to make a fallback for a certain number of blocks? I know how to make a fallback for the document structure, for example, assign the .no-flex class and transfer the document to float's or tables through inheritance.
What would be the best way in my case?

Answer 1

You can try, for example, flexibility-master (available on github) - a small script that substitutes floats instead of flexboxes in IE9.
