Side space for posts in mobile phones

I could not remove white space on both sides when I browse my website in mobile phones for posts? The previous solution worked for home page in mobiles but it is not working in mobile phones. Link given below. Please open this link in mobile phone to see the doubt.

Please advise.

Hello there,

Thank you for coming back.

If got it correctly, you’d need to add this additional CSS code to fix this padding issue on mobile.

@media only screen and (max-width: 780px) {
  #pgc-2981-0-0.panel-grid-cell {
    padding-left: 0 !important;
    padding-right: 0 !important;
