Reply To: Mobile first CSS

[Paulie_D]

Primarily because the design/layout etc for mobile is much simpler that on desktop etc.

If you design for desktop first you have to UNDO/RESET a lot of the desktop styling to rearrange things for mobile.

If you start with mobile first you enhance the design as and when the screen size requires.

Although file size is not an issue, it does make your CSS neater, smaller and easier to debug.
