i'am working on a site, when i visit the site with Chrome on my Smartphone (Oneplus 5t if its important) and under the Slider a small grey line just appeared (marked on the screenshot). When i view it online on my browser it does not appear.
I tried to do
border-bottom: 0px !important
on the fullwidth container and also the module block, but both didn't work.
how do i fix this?
Thanks in forward
