So far I've got to say this is an unbelievable piece of software!
I'm wanting to build a responsive site but I'm not a fan of the huge side to side designs. ( I feel it's kind-of-in-your-face, make all the sites look similar, kind of cookie cutterish)... What I want is to make a site with a max width of 1200 px, but that is responsive down to 325px.
Is this possible?

It looks like you can make it responsive from 1200 down to 200 pixels.

Thanks GreB,
I was just going to post that I was able to set the max width, but when I went to explain how... I couldn't find the option again? I know it was in DIMENSION but now I can't find it.
Can you tell me where it is?

Got it..
If I click outside the columns, and click on DESIGN link then open dimensions..
un-check WIDTH (AUTO),
uncheck MAX-WIDTH and set to what ever you want, my case 1200 PX

it seems that once you set it to MAX as i did above you can't access the option again?
That doesn't seem right... maybe I'm doing something wrong?

Sorry, I'm jumping my own gun here... If I click any column and then right click select GRID I have access to the GRID dimension I set before.
Cheers

When you have your grid width set or not in the working visual view of the pg there is that slider to your rt at the top that pointing down indicator above the pg view grab that and slide it on down. You have those device indicator icons on the left and a pixel readout of where the slider indicator is currently positioned. It goes right on down to the 200 pixels. This is the slide down line where you set your new added in breakpoints. Or remove break points.
One needs to be constantly aware of what current design feature element you are working in. Go to the inspector pane and when you mouse over an element it highlights that on the view. Double click on the one you want and that opens the design pain for inputting the setting to the function that you want such as the grid size. Often design elements settings will have to be adjusted and saved in each break point. You slide down until the rendering breaks and then adjust the settings at that break point, or ad a break point and adjust and then keep on sliding down to find the next need for a break point. Sometimes you will need to change the spans on an element so as to get it to just render single vertical columns rather than 2 or three side by side columns in a row so as to accommodate the smaller device sizes.

Thanks! Will try not to panic next time...lol
