Answer 1

'b' in 'by' should be capital in your code.
Also put this line inside the function.
var x= document.getElementById("thrd");

Answer 2

Try:
put your code in function,and 'b' in 'By' should be capital in your code.

function usage(){
var x = document.getElementById("thrd");
x.style.display ="none";
document.body.style.backgroundColor = "white";
}

Answer 5

Miss the first mistake is
var x= document.getElementbyId("thrd");
function usage(){
x.style.display ="none";
document.body.style.backgroundColor = "white";

}
That Is in getElementbyId the b should be capital
I mean it would be getElementById("thrd");
