Removing bad code from footer

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

Hi, I just made the mistake of putting this code block into the footer on my webpage, and now the header and footer are gone on the editor and I cannot remove the code. Any idea how to remove it?

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

I was able to fix this using safe mode.

with anyone has this problem, you can add this CSS to Design > Custom CSS to override above CSS, then header/footer will be back

/* bring back header footer */
.header, #footer-sections, header#header, footer.sections {
display:block !important; 
}
