How can I fix mobile cart layout issues on the Pipeline theme?

Hello everybody!

I am currently building a shop with the Pipeline theme and got some issues with the cart layout, especially for the mobile version.
It seems that the current Pipeline theme offers very few options to customize the layout of the cart. However, I know for a fact that the problem that I face can be solved, since I saw it on another website which uses Pipeline as well.
So let’s start with the desktop version, where I only have a rather small problem:

I recently added unit prices for my products which are shown right next to the product price without any gap.
Here is a screenshot:

I already managed to make the font smaller with my rather limited code knowledge, but I would like to put it below the product price. Does anyone have an idea how I can fix that?

But now let’s talk mobile, because there are some quite annoying things here.
While the desktop version offers price, quantity and the total price for every single product in the cart, the mobile version does not show the latest, as seen here:

I don’t think it’s too big of a problem, but it would enhance the usability if I can solve it. Here is an example of how it could look like:

That screenshot is from another website which uses Pipeline, but here you can see price, quantity and total price for the product in a very clear fashion (even though the desktop version looks quite similar to ours, except the issue I described before).
I took a look at the website’s code and it varies alot from ours, but only on the cart page. Could it be that it’s from an older Pipeline version and if so, is it possible to access the code of older theme versions?

Our website is www.spirits-of-blackforest.de with the password “Schwarzwald”
If you put a product into the cart, you better put one from the vendor heidenhofbrennei baßler. Since Pipeline does not offer a “fit to container” option for picture in the mobile cart, I have to adjust all pictures as well, but the Baßler ones are changed already.
The other pipeline website, where the mobile cart looks absolutely fine would be www.halter-edelbraende.de (if that helps to get a better understanding of my issues)

Does anyone have similar issues with Pipeline’s mobile cart or an idea how I can manage my mobile cart so that it looks like the last screenshot?
Thanks alot in advance!

Best regards,
