I was trying to style a website drop down menu (select tag) that would look the same on all browsers using css only. i removed the default arrow down, and i was trying to add a minimal arrow pointing down, and it took me a while to do it. Take a look at the pic.

However when i looked at the code. there was no code for that little arrow. I was confused for a few minutes, looking at both html and css. thinking how is this even possible, then i realised.

My f-ing screen was dirty. Dirt was similarly shaped like the thing i wanted to achieve. I was laughing at myself for a few minutes.

btw i did it in the end 😊 no dirt involved
