Answer 1

Whitespace between inline elements is compressed (or converted if it's something other than spaces) to a single space and displayed.

The W3C specification has more information:

This layout may involve putting space between words (called inter-word space), but conventions for inter-word space vary from script to script. For example, in Latin scripts, inter-word space is typically rendered as an ASCII space ( ).
