@panopano:
1. Border colors around text area: Checked your site, cannot find any borders. Let me know further.
2. How to use SVG logo:
For this, you’ll need to create a child theme. You can find more details on creating child theme HERE. Then in your child theme’s functions.php, add the following code:
function create_child_cc_mime_types($mimes) {
$mimes['svg'] = 'image/svg+xml';
return $mimes;
}
add_filter('upload_mimes', 'create_child_cc_mime_types');
3: How to responsively scale logo (it’s too big on smartphones):
Go to Dashboard=> Appearance=> Customize=> Theme Options=> Custom CSS box and add the following CSS:
@media screen and (max-width: 480px) {
.site-logo .custom-logo {
max-width: 100px;
}
}
