Page-heading remove?

Hello..

Im trying to remove the page-heading from each page on my website.

In the CSS stylesheet its

/*page heading*/
#page-heading { margin: 0 0 30px; display:none; }
#page-heading h1, #page-heading h2 { margin: 0; font-size: 2.154em; line-height: 1.3em; }
#page-heading:after { content: “”; display: block; height: 1px; width: 25px; border-bottom: 1px dotted #ccc; margin: 20px 0; }

I tried to add the “display:none; }” part but doesnt work..

What do I need to write?
