Stuck with it "showing error"

A class named silver-background should be defined within the style element and the value of silver should be assigned to the background-color property.

don’t know whats wrong with it i am doing it right but ???

you will need to provide challenge link and your code for someone to be able to help you

When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).
