Hello! Welcome to the site! I don't know who you are, but an enemy of Dusty is a friend of mine!
Also if you're practicing your coding, you'll want to make sure to set your text color as well. The site has several different themes, so depending on what theme people are using, the default text color might be black or white, so it can be invisible on the background you choose. If you set it specifically, regardless of the default, then you don't need to worry about that.
