CodeIgniter website ported to CodeIgniter 4

Theres a horizontal scroll on bottom, that looks like a sloppy CSS, on Firefox Mozilla, 1920 resolution monitor

Its caused by class row, for me, specifically by this:
margin-right: -15px;
margin-left: -15px;

(that looks weird)

You can see things I made with codeigniter here: itart.pro its not overly impressive as I have very little time to learn.
