To scale the inner containers on the page, you can set the width of the div container to 100% :
in your example:
#the-big-stories { display: table; table-layout: fixed; width:100%; }
further, if you want to scale images using child containers, just give them width: 100%; also using height:auto;
see below code of your code:

You will probably need to use media queries to really make the material inside play well together, but the container will scale using the browser, as will the internal div .
