Position and z-index on top = works, but on bottom = doesn't ( Fixing your header)


#1
#header {
    width: 50px;
    height: 50px;
    background-color: #00cc99;
    border-radius: 5px
    position: fixed; 
    z-index: 1;
}

Oops, try again.
Did you remember to give your #header a position of fixed?

#header {
    position: fixed; 
    z-index: 1;
    width: 50px;
    height: 50px;
    background-color: #00cc99;
    border-radius: 5px
}

But this works.


#2

#header {
    width: 50px;
    height: 50px;
    background-color: #00cc99;
    border-radius: 5px <- missing semi-colon
    position: fixed; 
    z-index: 1;
}

You are missing a semi-colon, which causes the line to be wrongly interpreted. Your second example does work, because then border-radius is the last property, and after the last property, a semi-colon is not required
