Hi @assant! Thanks for being here.
We need to know a few things to help us get started. First of all, could you tell us more about your website and the changes that you want to make to it? Secondly, where are you getting stuck?
Thanks for the additional details. Unfortunately, they still aren't enough to help you out productively, I'm afraid. You might want to check out the WordPress Support Forums since you're using WordPress. Otherwise, you might want to contact a WordPress developer who can help to walk you through the help you need.
