Problems with Header and footer in report with mPHP

I'm taking a look at mPHP to learn how to do reports with PHP, due to a case that occurred in my work, now I want to be cautious and learn to use such a tool, but I'm having problems (I tried to do similar to work) .

I can not put header and footer on the form, I've tried in many ways that I've seen on the internet, but nothing worked.

Can anyone help me?

Each variable I put here is in the same file, I'm just going to separate it to make it easier to see.

Code:

CSS:

$css="
    @page {
        margin-left: 20px;
        margin-right: 20px;
        margin-top: 15px;
        margin-bottom: 15px;
    }



    #cabecInicial{
        font-family: 'Century Gothic';
        color: #3864B2;
        background-image: url('imgs/cabecalho_relatorios_1_grande.png');
        background-position: right top;
        background-repeat: no-repeat;

    }

    #corpoCabecInicial{

MPDF:

$mpdf = new mPDF(); 
$mpdf->SetHTMLHeader($header, "E");
$mpdf->SetHTMLFooter($footer,"O");

$mpdf->charset_in='windows-1252';
