Albion trail to relegation rivals Cardiff after Nathaniel Mendez-Laing scored a screamer on 22 minutes.
He started the move in Cardiff’s half and brought the ball some way up the pitch before a one-two with Oumar Niasse.
Albion have offered very little again and have not had a shot on target.
They did manage a flurry of corners but were unable to capitalise.
Misplaced passes have brought groans of frustration from around the Amex.
The Seagulls need at least an equaliser in the second half or their Premier League status is under significant threat.
