Is there a way to make the Brine header partially transparent?

Site URL: http://www.dtr.media

Hello,

I was wondering if it is possible to make the header on the Brine template partially transparent? Right now I can either make it fully transparent or solid, but there is not an opacity adjustment otherwise. I wanted to know if it was possible to do through customization.

Thanks for any help

Hi. You can try using CSS background-gradient to set partially transparent.
