can't adjust margin

Hi!

There’s a 76px margin in the content part I want to eliminate

div id = content
role = main (don’t understand what this means)

I already tried

div#content {
margin-left: 0 px;
}

#main {
clear: both;
padding: 0;
margin: 0;
}

None works. Please check my site here https://protocolos.mdsinsure.com/deco/teste

Thank you
