There are many good grids online (1200px.com, unsemantic.com) that can be downloaded as PSD and used in web design in Photoshop. Now I have 2 questions in relation with this:
When I apply this template in my Photoshop document, they have small right and left margins, how do I adjust such templates to my needs because I want MORE white space, not 5-10px as the templates have? (do I go to canvas size and increase the size of canvas on both sides or else?)
How to use same 12 column grid template for mobile web design?
May be I am thinking the wrong direction, I am just confused, your help would be appreciated
