The Million Dollar Grid

The Million Dollar Homepage was a very successful and viral marketing stunt back in 2005 where people could buy 1 pixel worth of advertising space for 1 US dollar (with a minimum advertising surface of 10×10 pixels).
At the time, the million dollar homepage was implemented by using a single image which contains all ads stitched together, and an image map to link the image's various parts to their corresponding URLs.

The demo below is a silly recreation of the million dollar homepage which uses CSS grid.
The grid has one hundred rows and one hundred columns. Each reserved ad space is represented by a div element that's positioned onto the grid by using the grid-area CSS property. The original image from the million dollar homepage is used here, but I've made an effort to remove any explicit material I could find.
