Hi Folks... +1 for this issue... I'm new to the whole process, but have managed to successfully move a number of azw files to ePub to use in Google Play Books.
There are just a few where the font size is teeny-tiny and unreadable, and cannot be adjusted.
I have tried to do what is suggested in this thread - exploding the azw file and changing the 'rem' to 'em' - but seemed to have no impact.
I've attached a screengrab of the exploded azw - I changed the 0001.css file in text editor doing a find/replace of 'rem' to 'em'.
I've also exploded the epub, and done the same in there - since once the epub comes in to existence, it then has a stylesheet.css. But again - doesn't work..
any guidance here would be appreciated... it's driving me bonkers =D
