No autoresizing to fit the code
Render blocking of the parent page
This is a demonstration of how easy it is to create a fixed format eBook yet with dynamic sizing for whatever screen. The only issue would be the overflow of the text. This would easily be solvable if eReaders allowed for the viewport metadata to actually work. A native CSS specification for font-size is the "vh" (view-height) and "vw" (view-width). These font-sizes take in the resolution of the viewport (which if able to be set to "device-width" and "device-height" in eReaders) will adjust the font-size to fit itself exactly in the volume amount in its container regardless of the viewing window.
