Created Responsive Landing Page Template

There's no easy way to do this, unfortunately. The best solution I've seen is Edward Unthank's double div: http://edwardunthank.com/blog/marketo-responsive-method-marketo-double-div/

You can utilize it a few ways, including to still allow for the WYSIWYG to function, but it won't be as simple or clean as you'd like.

I used a totally different approach. I properly set up an additional container in the landing page template. Next I use @media queries to float every div on the left and make it 100% width. All with a few lines of CSS. The only thing you have to worry about is the order in which yo uplace elements on the page, so the order makes sense on a smaller screen.

Unfortunately, I tried Edward Unthank's double div and it did not work. We had to build our own. 

Champion, this is great! Thanks for your help. I will go ahead and give it a try. Thanks for the demo page. 

Thanks for the suggestion Diederik.  I had seen Edward's, but I did not see yours until now.  

I really like the method posted bu Diederik, I'm going to be trying this out.
