#btn{
margin-left: 50%;
}

Answer 4

Why that button comes outside the border..?if i remove float property, then it goes inside border-box..but in left side..

Answer 5

Remove the float, and add an <br> at the end of line 19.

Also, you don't need a <div class="form">.

You should use <form> instead.
