Sorry, the point I'm making is why use 100 and 102, is there any
visible difference?
Normally not, and 100% is the intended size. The reason for the
"slightly more than 100%" for h5 is that whatever the size 102% is
calculated from the h5 should end up _as large as or 1px larger_ than
the paragraphs (or whatever) its heading.
I would have thought the user would need to have a massive default
font size to see any. However I have noticed myself that the way the
browsers tend to size fonts can be quite strange. Sometimes a change
of 5% in scaling can result in the same font ending up the same size
however notably wider.
Exactly.
The particular layout it's used in don't have 100% font-size for all
containers all the way down the chain, and the "tip-over" changes when
sized down font-size on containers are subjected to resizing and used as
base for font-size on text-carrying elements - sometimes splitting
between 100% and 102%.
My entire site is used as a test-bed. I have hundreds of those "hardly
ever noticeable effects" baked in on my own site as part of continuous
testing of browsers, in the knowledge that browsers don't handle minute
differences exactly the same way.
The differences _I_ can then observe, will not disturb or distract a
visitor - unless that visitor (maybe a web designer) has particular
interests in why something looks slightly different in two browsers
under certain conditions.
I have received a few comments about such subtle differences over the
years, from fellow designers assuming I've gotten my values wrong.
That's great, as they are either confirming my own observations, or
informing me about something I haven't observed yet in a particular
browser under certain conditions. All good to know while I try to expand
my knowledge on how User Agents handle my work.
