html or xhtml: does it matter?
I know the basics: xhtml is an extension of html and the tags neeed to be lower case and closed etc etc. But I'm a non-techie and I'm using Sigil and the 'Add Blank html file' in the Book Browser seems to sometimes create an html and sometimes an xhtml file. I'm adding a "Also By Gregg Bell" section after the "About the Author" in my ebooks and I've looked at some of the books that have been made in the past and some have AlsoByGreggBell.html and others AlsoByGreggBell.xhtml.
Does it matter which it is? (I'm really hoping it doesn't.) And if it needs to be either xhtml or html how do I manipulate Sigil to do that? Thanks.
