[Theme: Takk] Replace cover text with logo

Hi all,

As php and CSS is foreign territory for me, can anyone offer a way to replace the following cover text “logo here” with a logo?

I like how the words “logo here” scroll in front of the background image (parallax). I wish to do the same but with a logo instead (using the logo on the brochure front cover below).

Any help gratefully appreciated,

George
