Tell us what’s happening:
the step says "Create a new CSS rule that targets the class [container] and set its [background-color] to black with rgb(0, 0, 0,).
my current code is
.container{
background-color: rgb(0, 0, 0);
} i’ve checked syntax, i’ve checked spacing, and ran it through chat gpt and chatgpt says it should be working but doesnt… 
any guidance?
