this seems like the wrong way to do this, what are you trying to offset and why
can't you cancel it out directly instead of offsetting?

[xiyuan, 2011/12/01 19:36:10]

This is to align center of #container div with its parent when the parent's size
is not known. You use left:50% and top:50% to move the child to center of parent
and then use negative margin-top/margin-left to align child's center with
parent's center.

I see. Can you add a comment about this then?

[xiyuan, 2011/12/02 21:24:20]

Done. Comments added.

the dot selection colors are kind of a mess, they should probably just be black
always with variable opacity (not via rgba)

this would make it easier to override rather than repeating 7f everywhere

[arv (Not doing code reviews), 2011/12/01 19:30:57]

This is not valid CSS.  0x7F is not a valid number

[xiyuan, 2011/12/01 19:36:10]

Cannot use black for aura because default deaktop background is dark and black
does not stands out.

Using opacity to avoid repeating color sounds good.

[xiyuan, 2011/12/01 19:36:10]

oops. Changed to use #7f7f7f and use opacity as estade suggested.
