Email Template not displaying Background Color in desktop Gmail

Email Template not displaying Background Color in desktop Gmail

The template display's fine in ZOHO's preview and on mobile, but not when displayed via a test email in Gmail. Anyone know what could cause this? I have the id templateFooter's background color set to blue, and I even tried changing the class footerContainer's background color. Neither display the correct color in Gmail.

This is the previewed version:
This is what display's in Gmail:
And here's some of the CSS I used:
.footerContainer{
/*@editable*/background-color:#007aff;
}
#templateFooter{
/*@editable*/background-color:#007aff;
}
