CLS issue Problem

Hello,
My website is a simple design.

But It showing CLS issue in google page speed.

Have you searched for the issue at Google?

https://support.google.com/webmasters/search?q=cls+

probably need a definition of ‘simple’.

Are you loading ads?
Are those ads in predefined-sized boxes?
Is anything on your page not the right size for the thing it’s loading?
