Help with CSS code to add 2 columns in mobile view

It looks like you’re using a page builder plugin (Kingcomposer) to build your site. I would suggest checking with the plugin support team to see if there’s a responsive setting you can adjust.

In case there’s not a simpler setting to adjust, try adding this to the customizer’s additional CSS section:

.page-id-2363 mixitup-gallery .col-sm-12 {
    -ms-flex: 0 0 50%;
    flex: 0 0 50%;
    max-width: 50%;
}

That code didn’t work it didn’t get columns unfortunately but put all the services section in one side and no in clients section

You “Meto” theme appears to be a commercial theme. The support we can provide here for commercial themes is very limited. It looks like there’s some sort of script that overrides CSS based on viewport size, so the solution goes beyond CSS. The page appears to be made with a page builder of some sort. I suggest asking for guidance through your theme’s or page builder’s dedicated support channels.
