According to my git history, it was a few months ago that I added the April Fool's page to my website hryprodva.cz. It was a day when I discovered some "interesting" filters in CSS, which are able to invert colours in whole document, just in one line of code. So I created a CSS class for HTML document, which applies this CSS rule, and set my program to assign this class to all main pages. I tested it with the current date, it worked, so I set the 1st of April as the day when the class would be applied to the page, committed to master and after some time I forgot about it.
So today it was a bit of a surprise for me too, when I saw the inverted colours on the main page. However, nobody complained about the "broken" design. So I wonder if everyone counts it as the first of April, or if all my players are colour blind and do not care. We shall see, there is still time until midnight when the filter disappears.
However... I am still thinking about what can be usefull on this CSS property, instead of april fool. Still cannot find a use case.
