Hello There,
Thanks for posting in! To make your navbar fullwidth, please add the following css code in the customizer, Appearance > Customize > Custom > CSS or insert this code in your child theme’s style.css (if you are using a child theme)
@media(min-width: 980px){
body.x-navbar-fixed-top-active .x-navbar-wrap {
height: 0;
}
.x-navbar {
background-color: transparent;
background-color: rgba(255,255,255,0.35);
}
.x-navbar .x-container.max.width {
max-width: 100%;
}
}
Please let us know if this works out for you.
