A couple of questions about custom css themes (both login screen and dashboard)

[Woolnut]

Hi All,

I have recently been tasked with getting together a new theme to be applied to the Zabbix log in screen and also some modifications on the dashboard...

I have found a tutorial on the forum which explains what steps are required for your custom css theme to be added...

I cannot figure out how chart2.php, for example, produces a dark background for graphs for some themes, and a light background for others. I have a theme I created that looks great, but the graphs are light when I want them dark.

Anyone have any insight regarding how this works?
