Header and footer in mpdf does not work for anything [duplicate]

I'm having a problem with mpdf and I really need help.

I can not put the header and footer in the report for nothing, even putting SetHTMLFooter and SetHTMLHeader does not work.

I tried version 7.0, 6.1, 6.0 and 5.7 and nothing ....

I am not a php programmer, this system fell on my lap.

Follow the code below:

$ CSS:

<style>

                @page {
                    margin-left: 20px;
                    margin-right: 20px;
                    margin-top: 15px;
                    margin-bottom: 15px;
                }



                #cabecInicial{
