Well, I've already looked at various websites how can I do this? Most people say that it's for me by
body, html{height:100%;}
footer{width:100%; bottom:0; position:absolute;}
But when I do this, it stays at the bottom of the screen, not at the bottom of the page.
That is, it sits in the middle and overlaps the content.
Does anyone know how I can make it fixed?
I'm working as follows. It separates a file "Header.php", "Footer.php", and then I include in the content file
<?php include "header.php"?>
//conteudo
...
<?php include "footer.php" ?>
