Broken Responsibility after changing size of Headlines in CSS

[parfumylacno]

Hello,

Please, can anyone help me with my eshop with perfumes - and with broken Responsibility in mobil devices after changing size of Headlines in CSS. I had only make few changes in CSS - size of H1 and H2 headlines and some others little changes = and everything seems in order, that all works good.

But then  - after few months - i found out that there are problems in mobile devices (In PC is all alright) -

• Pagination of all product list are pour together, and is very dificult to click on accurate number of page
• Some buttons like add to cart in product details - in list of all products - are beyonds border of another product

You can see it best on this site of perfumes: https://www.parfumylacno.sk/parfumy-eshop/parfumy-fm-pre-zeny
Or in attachment pictures

Please, is there some simple "hacks" or solution how to repair it?

Thank you very much,

Have a nice day to all

2 bads rules found anout height: 30px for pagination.
A quick fix

.labpagination {
    /* height: 30px; */
}
.labpagination ul {
    /* height: 30px; */
}

and the other problem is
.bbox, .cbox {
    height: 45px !important;
}
This should use a responsive rules to disable it on mobile(and tablet).
But i already used linelabs template, and they are not really finished and you
have some work to fix all css.
