Hi,
We have checked your website. At the footer, you have added some reviews with the help brb collection widget (may be with the help of some plugins) https://screenrec.com/share/XVxEqoYBHc. They have applied a with that is applied to mobile view also. We have tried adding our CSS but it is not working you can try by adding the below code at Appearance -> Customize -> Additional CSS
.widget.brb-collection-widget .rplg {
width: 100% !important;
}
Thanks
