Hello, I am trying to change the background color of the footer on my AMP page, from the default baby-blue to one of my brand colors (#4c4d4f) while also changing the footer font color to white (#ffffff). However, standard HTML code doesn't seem to work. I tried using the below code, but when I hit save, and the page refreshes, most of the HTML disappears. What am I supposed to do instead? Thanks!
<html>
<head>
<style>
body {
background-color: #4c4d4f;
color: #ffffff
}
</style>
</head>
<body>The background color can be specified with a color name.</body>
