Dude, so I'm just trying to get my mobile site to look like my computer site. I made the site through readymag.com, I don't have much experience with coding, only some html and css experience from a coding 101 class. very basic. But, so my problem is, I have my logo big, and then when you scroll down, it shrinks and then is pinned to the top of the page along with my navigation bar. But when making the mobile version, readymag doesn't let me add on-scroll animations, so the logo is just small at the top of the page and the rest of the page is blank. Looks really dumb lol. So, I can add in coding to my site, but I have no idea how to code animations, and I can't find it online. Please help!

(my description sucks, so to see what I'm talking about, go to lindseyfletcherdesign.com and view it in both desktop and mobile versions, you'll see what I mean!)
