CMS overlay on click (technical prototype) yep, its responsive ;) As you can see, every CMS item has a different grid-size. I achieved this with very little custom CSS code. The code is implemented inside the body at the very bottom. If you want every item to be the same size, just delete the custom code. Thats it. Keep in mind that links inside the overlay won't work. As soon as you click anywhere in the overlay it will close itself instead of triggering the link. If someone figures out how to achieve this, feel free to write it down in the comments and I will implement it in the project.
