Uncomplete CSS property descriptions

I made this comment under a different title which received no response.  If
my perspective is of no value to this community, I'd prefer someone tell me.
I came here because I figured it would be nice to learn to code properly if
I am learning anyway.  My basic point here is that a standard should define
all relevant terms of art, without which it leaves people guessing.



Now that the CSS properties are essentially wrapped up, I figured I'd give
them a test run from the newbie's perspective.  I just wanted to take one at
a time and stick them in a style sheet to see what happens.  I don't know if
it helps or if I am just outside of the target audience, but for me certain
things are not clear.  I include the first few properties below. If this is
helpful, I'll continue.  Feedback is appreciated. 

align-content
Aligns a flex container's lines within the flex container when there is
extra space in the cross-axis, similar to how justify-content aligns
individual items within the main-axis.

I don't know what a flex container or flex item (from
http://docs.webplatform.org/wiki/css/properties/flex) is.  The term is not
defined in any glossary on the site. 

align-items
Sets the default alignment in the cross axis for all of the flex container's
items, including anonymous flex items, similarly to
how justify-content aligns items along the main axis.

Same with cross and main axis.

align-self
Allows the default alignment to be overridden for individual flex items.

alignment-adjust
This property allows precise alignment of elements, such as graphics, that
do not have a baseline-table or lack the desired baseline in their
baseline-table. With the alignment-adjust property, the position of the
baseline identified by the alignment-baseline can be explicitly determined.
It also determines precisely the alignment point for each glyph within a
textual element.

I get what the baseline is (thanks to
http://docs.webplatform.org/wiki/glossary/main), but that doesn't help me
with a baseline-table.

alignment-baseline

Conducting a search, a discussion of this comes up under SVG, but there is
no CSS reference to give me a clue as to how I would use this, or what
happens around this, although I suppose I could play to figure this out a
bit.
