auto (to solve) : top

+
|
|
auto (to solve): margin-top
|
|
+
|
|
0 : border-top-width
|
|
+
|
|
0 : padding-top
|
|
+
|
|
auto (to solve) : height
|
|
+
|
|
0 : padding-bottom
|
|
+
|
|
0 : border-bottom-width
|
|
+
|
|
auto (to solve): margin-bottom
|
|
+
|
|
200px : bottom
|
|
=============
|
|
300px : height of containing block
|
|
|
|
"
|
|
'top' and 'height' are 'auto' and 'bottom' is not 'auto',
|
|
then the height is based on the content per 10.6.7,
|
|
set 'auto' values for 'margin-top' and 'margin-bottom' to 0,
|
|
and solve for 'top'
|
|
"
|
|
|
|
so this brings:
|
|
|
|
|
|
auto (to solve) : top
|
|
+
|
|
0 (solved): margin-top
|
|
+
|
|
0 : border-top-width
|
|
+
|
|
0 : padding-top
|
|
+
|
|
100px (solved: based on content) : height
|
|
+
|
|
0 : padding-bottom
|
|
+
|
|
0 : border-bottom-width
|
|
+
|
|
0 (solved) : margin-bottom
|
|
+
|
|
200px : bottom
|
|
=============
|
|
300px : height of containing block
|
|
|
|
so top will use 0px
