Help with background image only on Home page

Hey – sorry to be such a noob!! Just getting into WordPress and was *so* happy to find this plugin. Working like a charm on my home page, but it’s also on all the rest as well. I did find this older thread:

[url]ttps://wordpress.org/support/topic/can-the-plugin-be-limited-to-just-the-home-page/[/url]

asking the same question, but I wasn’t able to get it to work, though I doubt I was doing it correctly! I cut and pasted the lines of code, such as:

#fsb_image { display: none!important; }
.home #fsb_image { display: block!important; }

…into the very end of my style.css file – is that the correct way to do it? Do I need to replace anything in the code, such as the image title in place of #fsb_image?

Sorry to ask such a dumb question – I would be most grateful for your help!

And thanks again so much, Pippin, for this fantastic plugin! Made all the difference in the world for me.
