R/webdev could not solve this challenge: A “Is it Friday” website, no JavaScript

The challenge is to create the functionality using only html and css - No serverside rendering that serves a css file on friday - No special CDN setup - No image loading that serves another image on friday Just html and css

Does it need to automatically render whether today is Friday... something like this is silly but kinda works -- requires you to set the date though which I'm not sure is allowed.

<input type="date" min="0001-01-05" step="7" value="2023-07-03"> // valid for all Fridays starting 1AD

Then you can use some css when invalid: input:invalid { background: red; }

or whatever other styling you want, maybe slap some content on another element... you get the point

Could they not solve it because it’s impossible?

Seems like asking someone to draw a red line on a white piece of paper with just a black sharpie marker.
