background: linear-gradient(gradient_direction, color 1, color 2, color 3, …);
The first argument specifies the direction from which color transition starts - it can be stated as a degree, where 90deg makes a vertical gradient and 45deg is angled like a backslash.
You were telling the browser that you want a linear-gradient as a background and you want it to go in the 35 degrees direction from the color red to yellow to rgb(255,204,204).
This is not what the challenge wants though , do you see? The challenge wants you to make a linear gradient at 35 degrees that blends only 2 colors: #CCFFFF and #FFCCCC
I’m trying to avoid giving you the answer directly because you will just quit if I spoon-feed you answers and later you are unable to complete the harder challenges.
I hope this helps and if not, please respond and I will take another look.
