Question: I run this program and after that i get "Errors exists do you want to continue". Then i click yes and i get "Hello world" in the console. Which was the project i ran previously. 
Anybody knows what is the problem? 

```
#include <iostream>
#include <typeinfo>
using namespace std;

int func() {
    return 42;
}

int main ( int argc, char ** argv ) {
    auto x = func();
    cout << x << endl;
    cout << typeid(x).name() << endl;
    return 0;
}

```

Answer: 
Since you're problem is with the style you need to make a change to the CSS. 

In your case you want to get the menu on top of all other objects. Just give the menu container a large `z-index`.
Additional question about the same site. When scrolling through the site, the menu-item should change with every slide it passes. At this moment the last clicked menu-item is highlighted, even when scrolling through to the several slides. Is there an easy way to make that work in CSS? Or would that be possible by just adding a *jQuery.nav.js* to the *index.html*?
