All this looks set to change thanks to flat design. Characterised by a simple, pared-down style, flat design is one of the hottest topics on the Web today. Stripped of the in dimensional quality previously favoured by many interface designers, flat design uses simple shapes instead of ornamentation. In place of glistening gel buttons and sweeping gradients, flat design uses crisp blocks of solid colour. Flat design leans towards minimal typography: unadorned sans-serif fonts are the order of the day.
