Hey @paul2009!
That just fixed it. You were swift. Thank you very much!
The code I had before was:
background: radial-gradient(50% 50% at 50% 50%, hsla(245deg, 42%, 42%, .89) 20%, rgba(0, 0, 0, 0) 100%);
And I had to remove "deg" after 245.
Another question is how did you figure out that this line was giving the syntax error? Usually I would get a note in red text inside the custom css editor telling me which line is causing an error, but this time I did not get a prompt.
Do you use a different way to troubleshoot css syntax errors like this?
EDIT: I know you mentioned developer tools, but is there a specific tab there that shows errors? It can be overwhelming but I'm slowly learning my way around it.
