Relative font-size is incorrect page 75

[bazzaxiv]

The font sizes xx-large, x-large and so on are fixed sizes. not relative. Changing the base font size has no affect on them.

Thanks for the heads up! It looks like you are right. I'll need to look at it in a little more detail to determine the best way to fix it and how to move forward. It probably won't be until this weekend.

Thank you!

This is now noted in the official errata here:

I'll need to do some work to fix the narrative to correct this, but once I do I'll close this out. It should be fixed by the time we do the next ebook update. Thanks for reporting it!
