Re: responsive grid with responsive images inside them

[DavidX]

I am fascinated by responsiveness, but it is a challenge, especially with the pressure to complete the editorial side of things.
When you refer to the columns that are set to 100% in the 1200px section, do you mean just the column classes (e.g., one-fourth etc.)?
Are there some examples of this kind of code and how it works for various designs?
