Remove Default Header and Footer and add custom header and footer with css

[jatindersingh81]

I want to remove default header and footer in chrome with css and add my own header and footer on each page.

I tried the following

@media print, screen {
/#Header, #Footer {
display: none !important;
}/
}

and added the link to the css like the following

Thanks in anticipation
