A.22 Em spaces, en spaces, and so forth
This is my first foray into the "Production and Digital Technology" appendix, woo!
I was proofreading a friend's website and suggested that he add em spaces (which are the width of a capital M) or en spaces (half the size of an em) between certain text elements that seemed too close.
Chicago gives the Unicode numbers for a nice variety of spaces, and we found the HTML entities ( and ), but we couldn't get them to work. Chicago warns that these spaces are more reliably used in print than online: they are not available in many fonts, limiting their usefulness in electronic documents and publications.
The em space The em space can separate a run-in head from the text.
The en space The en space is a smaller space that can be used similarly.
