Hello,
there are many differences, starting with the size and typeface, ending with the appearance of an extensive menu, where the appearing element overlaps the main categories of the store. Smaller differences are also lacking, such as the border of products in the Best Seller boxes.
In the demo version, for example http://kute-themes.com/html/kuteshop/html/ we are dealing with a slimmed-down version of the site in terms of source code, I mean even CSS files, where the file is much smaller, while the additional files are loaded directly via CSS, not import () already in the style sheet. The downloaded main CSS file weighs about 900kb - it's a lot, the one visible in the demo version is just over 200kB.
I think that the downloaded package is prepared directly for all possible versions, ie DEMO1, DEMO2, DEMO3 etc. I would only be interested in template No. 1, ie DEMO1 with a full set of additional files like cart, login, product card, category view, etc. .. But as I mentioned only the DEMO1 version, thanks to which the service will become much lighter ...
I am sorry that earlier post, I am not an eagle of English, I wrote from my hand - this post was written using Google translator.
