The Rise of REM
As web designers and web developers we live in a world of pixels, such is the state of display technology. We also like to make things easier to work with and in a world of small and large viewports the pixel had to go. When we consider that the primary mode of the web is text it makes sense to size the internets around font-size. Some love the clarity of ‘px’ and some like the relative sizing of the ‘em’. Others must have thought it a bright idea to give us both so we get the ‘rem’. Problem solved. (*sigh*)
