Header and Menu on Each Page

Hmm… I’m new to all this, so perhaps I’m not using the correct terminology. I currently have the Longevity theme and have created my front page to look like the demo, but the banner, call to action, and thumbnail pics are showing up on each page. I’m hoping just to have that on the front page so that the content is what displays on each individual page.

I found an article (https://www.shapedpixels.com/blog/how-to-display-widgets-on-select-pages-only) that I’m about to try to see if that will solve my question, but if you have any other suggestions, I’d love to hear them 🙂 Thanks!
