Stop Floating Logo

This is my way to achieve that:
Add the following code in your child-theme functions.php

add_action('__header', 'tc_header_header_start', 0);
function tc_header_header_start(){
echo '<div class="tc-header-container container">';
}
add_action('__header', 'tc_header_header_end', 40);
function tc_header_header_end(){
echo '</div>';
}

and get rid at least of that 50px of padding left here:

.tc-header .brand {
float: left;
text-align: center;
margin: 0;
padding: 0 0 0 50px;
font-size: 16px;
font-weight: 700;
}

I don’t recognize that rule, is from the original customizr or is something you changed in the original file?

It you did that, you better use a child theme and make all the changes in its style.css otherwise you’ll lose them on each update…

Hope this helps
