Remove vertical header width Supply Template - CSS Troubleshooting

Site URL: http://www.constantinetohme.com

Troubleshooting and trying to get the header off of one page on Supply Template. The best I've arrived at is the code below but it only removes the navigation / logo etc... But the width of the header still occupying the screen. Honestly, no idea what can be done / what is going on, any advice appreciated! 

<style>
 #header, #footer, #mobile.bar {display: none !important;}
</style>

It seems you solved?

Hey.. thanks for the reply, no it isn't solved 😞 you maybe can't tell because the page/header background are the same color on my landing page, but the content is still offset by the header margin somehow - if you click through to 'treatments' you will see the width of the verticle header more clearly.

Like I said, for some reason on this template the code only removes the navigation links/logo/title 😞  If the home page were without the header the image would be all the way to the left. Or is it showing up differently on your browser? Any suggestions?

[Here] are images of how it's showing up on my screen using the code.
