I believe it get’s fixed in later movies.

Can you post your code, maybe there’s something odd going on?

Haha, happened to mee too when I posted my code for the first time :)

Where do you write your code, on a code editor? I can’t find anything strange in your code. Did you save your file and reload the browser?

I’m a newbie too so I’m maybe not best guy to give advice. Anyone else have opinions or able to lend a helping hand for two up and coming superstars of a coding world? :)

Glad I could help!
