More adjusting HTML of Ebay store to be mobile friendly - first steps improved mobile but borders too thick, 1 photo squished, 2 photos out alignment, Mobile HTML Options

Dear HTML help forum,

I am here to ask a few questions about what needs to be changed in my HTML markup for my eBay store to be more mobile friendly. I have already started taking some steps and still have some specific questions about content that is not adjusting properly to mobile from within the eBay app on android and iPhone. I am a huge newb to any kind of HTML, CSS or anything else related, so I have been following simple instructions from a few different websites that help with this topic. I will list a link to the desktop website, a link to screenshots of the desktop website and mobile website from within the eBay app from android, my questions, and the steps I have already taken.

This is the webpage I've used to test the HTML formatting: https://www.ebay.com/itm/163162615054. For me, it works on desktop from a mac in Chrome, Firefox, and Safari.

These are the screenshots: https://imgur.com/a/c9UfGhx.

1. Can I force the border to resize itself to the constraints of the mobile device?
2. Why is my logo image squished? What can I do to get it to resize properly?
3. Why are my "Blush" and "More" images out of alignment on mobile only?

So far I have added:
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<style>
img {
max-width: 100%;
height: auto;
}
</style>

I do not know where to start with questions 1 and 2. For question 3, I have tried to find the HTML formatting that is different for those images and deleting it but to no avail.

Thank you for taking the time to read my submission. I appreciate any feedback.
Thank you,
Vanessa

I would like to update that I have made the logo and "Explore The Shop" images smaller on desktop which solved that problem. For the 2 rows of 4 images, I changed it to 3 rows of 3 images which solved that problem.

The only thing that I haven't figured out is that the borders don't resize completely on every phone. They still resize but there is a tiny bit of horizontal scrolling to see all of the border, but you don't have to scroll to see the images and descriptions and all. It would be optimal if I could fix this border issue, but I realize that I may not be able to perfect it on every phone, especially since it's within eBay's parameters as another user pointed out.

Thanks,
Vanessa
