Tell us what’s happening:

To make the input and textarea elements blend in with the background theme, set their background-color to #0a0a23. Then, give them a 1px, solid border with a color of #0a0a23.
(I have exactly followed instruction whats wrong?)

Hi there!

The above properties and it’s values are floating in the air. Didn’t have any selector.
You need to add input and textarea combined selector and add that styling for background and border within it.
@SoumenDash7

That needed to be written in curly braces right like styling element is not it?

That above is a example of two combined selector. instructions for the challenge step wants you to style input and textarea background and border with required styling.
