I have been organizing products from a SQL table into
<div class="col-sm-6 col-md-6 col-lg-3 col-xl-3 main_item_div mt-4 mb-4">
divs.
The issue I am encountering is that on mobile devices, the col-sm-6 class does not seem to be functioning properly. The products are consistently displayed one below the other instead of two divs side by side.
If you want to see this problem in action, you can visit my website at this link
You can find these divs under the "Újdonságok, akciós termékek" title section.
Your feedback and assistance would be greatly appreciated!
