Well, i want to get an effect that, when i clikc a section of my HTML top buttons, the page jump to a new page (inside of my own page), but only change the body, foot... and remain the top.
Like this example:

When you click a section, just change the middle part of the webpage.
Thanks!
I think you misunderstand what is happening on the example site you have provided. When you click on a link it is going to a different page. What you are seeing is a fixed background so it just looks like only the body content is changing.
You can achieve this with some CSS:
body {
background-image: url("background.jpg");
background-repeat: no-repeat;
background-attachment: fixed;
}
