My image on the color section is not responsive on mobile

I’ve tried the codes you provided on other suggestions but it didnt work to fix it. cleared cache multiple times as well.

Have used this code:
@media only screen and (max-width: 767px) {
#who {
background-size: 277% 85% !important;
background-position: -337px 85px !important;
}}

Didn’t work.

1. is there an option for me to upload a portrait image for mobile and then keep the current image for desktop and tablets?

2. my contact form from enfold isn’t working and isnt sending out any emails. have tried another form which worked: POWr contact form, but that’s a paid option and we’d like to use the contact form that came with the theme. Could you please look into this?
