Hi @adipure 

Go to your Online store > Themes > Edit code, open theme.css file and add this code at the bottom.

@media (max-width: 767px){
.tt-mobile-header .tt-logo-container { margin-bottom: 0px !important; }
}

Hello There,

1. In your Shopify Admin go to online store > themes > actions > edit code
2. Find Asset > theme.css and paste this at the Top of the file:

.tt-mobile-header .tt-logo-container {
padding-bottom: 0!important;
}
