I just started a new document and compiled it with the default ebook format for epub 3 to preview it. I noticed the sections with the style of “Emphasis” had a larger font size than the rest of the text.
It is easy to fix by editing the format, but I’m a bit puzzled why the default would come out like that.
Looking into the html that is produced, I see that both “chapter-title” and “titled-section” set a font size of 0.92rem, while “emphasis” sets 1rem. “body” also sets 1rem, but “chapter-title” and “titled-section” sit directly inside the body tag and span the whole document, rendering that moot.
My first thought was that those were intended to only span the tite part and not the text, but now I’m not sure about that. Another theory would be that those sizes were originally “em” (relative to the parent element) and then changed to “rem” (absolute) without changing the way they are used. But then, why set the font size for everything to 92% of what the user has set their eReader to in the beginning? That’s a bit rude, in my opinion.
Um…what is going on here?
And on an unrelated note, <em><span class="emphasis">... seems a bit redundant.
