i wanna leave Blue Box #1 Space as it, without editing anything!
and i wanna replace Pink Box #2 (include Follow/Friend Me space And all bottoms) to Footer (white box #4)
then i wanna use the empty space in (pink box #2) to make the (Black box #4) width=100%
by the way the ( RECENT POSTS ) i suggest to put it under the (blue box #1) in moving line from right to left, because it is important to make it seen as possible as i can
