Answer 1

html, body {
height:100%;
width:100%;
padding:0px;
margin:0px;
margin:0px;
}
and now for your block set
.block {
width:100%;
height:100%;
}

Answer 2

It is enough to set for the block:

block {
width:100vw;
height:100vh;
}

Answer 3

You can write id for example
#first{
width: 100%; /*this width will stretch to 100%*/
height:100%; /*this is the height at 100%*/
}
And then you will have a div in which your very first screen will be and you will write there
div id="first"
here is the first block
/div
