Mobile Navigation CTA size and colour

Site URL: https://homevetbondi.com.au/

Hi All,

First time poster. I've never coded before but learning! 

I've got the following codes 

.sqs-mobile-info-bar-hide {
-webkit-transform: none;
transform: none;
}
.sqs-mobile-info-bar {
z-index: 10;
}
@media screen and (max-width:767px) {
/* show button */
.header-actions {
    display: block !important;
}
.header .header-actions-action--cta {
    display: block;
}
/* logo width */
.header-title-nav-wrapper {
    flex: 50% !important;
}
}

I'd like to change the colour (AAB6BD) and size of the button so that the logo becomes larger on mobile site.

please let me know your thoughts. Would be much appreciated! 

Warm Regards,

Anthony

If logo larger, call button will overlap logo...
