"Correct" Way to Add Custom CSS?

[Amaury]

Not so much "correct," which is why it's in quotation marks, but what the majority of people do.

For example, the Folder Picker text on the private.php page isn't controlled by blockhead_color by default; it's controlled by something else that I don't remember now.

To make it be controlled by blockhead_color, I would do this:

.popupgroup .popupmenu a.popupctrl {
    color: {vb:stylevar blockhead_color};
}

However, I've seen some people that do things like this:

.popupgroup .popupmenu a.popupctrl { color: {vb:stylevar blockhead_color}; }

.popupgroup .popupmenu a.popupctrl {
color: {vb:stylevar blockhead_color};
}

I always do it the first way I listed here.
