header.php

hi guys

I have edited my header.php file, to place an image in top right of page, but, when I replicate code for top left,
it does not work. I want images in header on top left and top right.

<style>
body.custom-background {
    background-image: url("../../../new logo23.png");
 
    background-position: right top !important;
}
 
</style>

if I include background-position: left top !important;

it does not work, ? (I only end up with one image in header)

thanks
