Hi there @saeid.marouski — this looks like some really good work — well done!
You have certainly got the main parts of the exercise right, albeit with some different colors; that is fine! The one thing I’d do is remove the padding around the card div, i.e. get rid of the padding: 1em;
declaration out of the .card { }
rule. I thought that looked a bit strange.
