The window blind (10) includes a fixing rail (20) mountable to the top of a window frame, and a pleated fabric material blind (11), having a rigid top rail (12) parallel to the fixing rail. The blind includes two control elements (21,21') with a top control cord (30) controlled by the first control element (21) that allows the top of the blind to be lowered and raised to form a gap between the top rail and the fixing rail. The second control element controls a bottom control cord (40) that allows the bottom of the blind to be raised and lowered.
