Hi,

I have added the following code to my custom css, following an idea found in the forum

/*couleurs de fond du logo en hexadécimal container_header*/
#container_header {
background-color: #721e1e;
}

Works fine, till I adjust the style of the template to "sticky header"
If I scroll down the page, the background-color instantly changes to black.( in fact to #273233 )

What did I miss?

Regards,
Jean-Pierre
