How do I edit the mobile view without changing the desktop view settings?

Hi, 

I just need help with making sure my website content is optimised for mobile. 

Whenever I change embed videos from a third party platform (not Youtube or Vimeo), the size and placement are changed in both the desktop and mobile view. I'm using the fluid engine 7.1 version. How do I resolve this?

Thanks,
Cagney

I can't see what's going on here. But when using Fluid Engine you can adjust the block layout on mobile by editing the page and then clicking into the mobile view (top right). As a general rule, this operation of editing the mobile layout is vital for websites running fluid engine, every time you edit the desktop version.
