When you type a property, you get a list of all possible values. It would be GREAT to visually flag the initial value differently to all other values in the list.
Background-size shows
auto
cover
contain
<length>
<percentage>
<length> auto
auto <percentage>
<length> <percentage>
<percentage> <length>
This possibly gives a false impression that these are the total number of options. In reality there are others such as:
auto (default)
cover
contain
length (auto)
length auto
percentage (auto)
percentage auto
length length
length percentage
percentage percentage
percentage length
Another example is background-repeat. The values shown are:
repeat
repeat-x
repeat-y
no-repeat
space
round
Again, there are other options
repeat-x (auto)
repeat-x auto
repeat-y (auto)
repeat-y auto
repeat (repeat)
repeat repeat
space (space)
space space
round (round)
round round
no-repeat (no-repeat)
no-repeat no-repeat
Another one is background-position
0% 0%
left top
center center
right bottom
There are a wide range of options here
length length
length percentage
length keyword
percentage percentage
percentage length
percentage keyword
keyword keyword
and four keywords...
keyword length keyword length
keyword percent keyword percent
