What you are trying to do here is create a CSS rule that includes multiple selectors.

Grouping Multiple CSS Selectors

for selecting 2 classes i.e cap and sleeve, is the following code valid?

.cap .sleeve {
display: inline-block;


HI @shivamborkotoky69 !

Welcome to the forum!

Please carefully reread the first sentence of the article that was shared with you.

To group CSS selectors in a style sheet, use commas to separate multiple grouped selectors in the style.

I am looking at your code here, and it is missing something

Once you add that in, then the test will pass

Hope that helps!
