Welcome to the forums, @begummaimuna0.
Unfortunately, your post has far too little information for anybody to provide a helpful answer. You’ve posted in Design & UX, but mentioned JQuery, which would normally be a question for the JavaScript forum.
Please provide full details of what you are trying to accomplish, and where your problem lies. Either post a link to a live page which demonstrates your issue, or post the full code here. (This post explains the various ways you can do this.)
