Reply To: Logo size on mobile view

@hjhatch: Hello John,
Please remove the CSS Code you have added for the logo and
Go to => Appearance => Customize => Additional CSS and add the following CSS Code.

.custom-logo {
	max-width: 250px;
}
@media screen and (min-width: 1024px) {
	.custom-logo {
	    max-width: 500px;
	}
}

You can change the width according to your choice.
Let me know if this works out!
Kind Regards,
Skandha
