XF 2.2 How do I have alert toggle icon always visible?

[dtrumbower]

Apparently, in 2.1 the alert pop up had different background color. In 2.2 the alerts use a toggle icon, but one has to hover in that area to see it. What would be the CSS to keep it always visible?

Thanks

Added to extra.less:

.alert .alertToggler
{
    opacity: 1 !important;
}
