Edit HTML of lander to change around links

[PMK11]

I have this lander page I think is great but I need to edit to add my own links in. My knowledge of HTML and CSS isn't that great, I'm still newb/intermediate at it. Here's the page- for pop ads, which lines would I need to edit in the code to add in my offer link? What about all the javascript? I disable bing and facebook pixel in the HTML code because I don't need it, but the CSS references confuse me. geniustrainer.net/welcome.html? aff=4028&theme=1501&clickid=776b9cf176bd4e2288ae9872e0c324d611454&pub=25903&sub_pub_id=
