How to make a hat for the whole crane?

Question

css

It is required to make the site header full screen, like here .
And I want the slider to fill the entire screen.

Answer 1

.header {width:100vw; height:100vh;}

Answer 2

if you don’t understand what you need to first open the developer panel in the browser and see how the menu and slider are made on this site, then how else can you explain or suggest how this is done for the whole

tap

!!!

Answer 3

Ctrl+U, F12 - look at the source and styles and do the same.

Answer 4

.block {
width: 100%;
height: 100%;
position:  absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
}

But in order to achieve such effects as there, you still need to twist js a little.
