Learn CSS Colors by Building a Set of Colored Markers - Step 53

Step 53 is giving me a headache not what error I have caused. Please advice where I went wrong.

.red{
background: linear-gradient(90deg, rgb(255, 0, 0), rgb(0, 255, 0)rgb(0, 0, 255));
}

hey,

add comma before third rgb()

Thank you very much I will do that .
