I am looking to make my website a modern looking one. I would like to put the table of contents on the top of my website, like that guy did on his one - Home Page
The point is, when someone click on someone's profile, the webpage must open in the same window, not in a different one, the same way this guy made his own. Please tell me how to do it.
I am sorry if I explained what I want badly. Please tell me if you need more info.I will try to post images too
Here is my site - Dyulgerovs' chess webiste
