If you’ve spent any time building responsive websites with fluid grids, you will have encountered the shock of seeing your beautiful portrait layout distort when viewed in landscape mode (or vice-versa.)

Many great advice on how to approach a responsive web design.

When you design or build a website, app, icon or UI element, you’re designing to a grid. It doesn’t matter if that grid is pixels, points, percentages, inches, centimetres or some other kind of measurement. It can be as abstract or specific as you like. It’s still a grid.

Everything indeed.
