Link Theme Issue

I asked this question in the theme’s dedicated forum and got no response. Can anyone help over here?
I found a code here That was supposed to allow me to swap the title for a logo. I inserted it into the css stylesheet but it has not worked. I would rather remove the title and tagline from the homepage and not put the logo there because I have a custome background that I’m trying to use that includes the logo already. How can I erase the title from the homepage?
