Hi there,
Thanks for writing in! You can add this under Custom > CSS in the Customizer.
@media only screen and (max-width: 600px) {
.x-brand {
margin-bottom: 15px;
}
.masthead-inline .x-btn-navbar {
clear: both;
display: block;
float: none;
margin: 15px auto;
width: 50px;
}
}
You can change the max-width: 600;
value to higher to get this work on higher screen size too if needed.
Hope this helps.
Cheers!
