Adding Pictorem Gallery

<div class="iframe-container">
   <iframe style="width:100%;padding:20px;max-width:1400px;min-height:1000px;" src="https://www.pictorem.com/gallery/Jason.Fink.Photography" allowfullscreen frameborder=0 style="border-width:0px;"></iframe>
</div>

Ok, so that's the code Pictorem.com provided to add my Pictorem storefront into my website. As you can see on the page provided, the storefront is  very small and not functional at all. Nothing I change in the embed code's style settings regarding the width or height seems to make a difference. I'm wondering if I need to add some CSS code for the iframe-container class, but not sure where to start. Any help would be appreciated. 

EDIT: OK, I think I got this. I had to create a new class inside the iframe tag. Called it "mystorefront", then used this CSS. For some reason, the style attributes inside the iframe tag were not taking.

.mystorefront {
  width: 100%;
  max-width: 1400px;
  min-height: 1000px;
  padding: 20px;
  border-width: 0px;
}

Add this to Design > Custom CSS

iframe.mystorefront {
    width: 100%;
    max-width: 1400px;
    min-height: 1000px;
    padding: 20px;
    border-width: 0px;
}

Hi Jason, did that work? When someone orders on your site are they ordering on Pictorem?
