Marta Template: How to centralise the header (primary navigation) and make it sticky at the top with solid background?

Add to Home > Design > Custom CSS

.Header-inner--bottom>div {
    flex-direction: column;
}

Thank you! The centralise worked. 

I also need the header to be fixed at the top with background when I scroll down, appreciate if you can help on the code.

Thank you!

Do you use Personal or higher plan?

 $(window).on("scroll", function() {
        //Sticky Header start
   		header = $('header.Header.Header--bottom');
        if ($(window).scrollTop() > 30 ) {
            header.addClass("sticky");
        } else {
            header.removeClass("sticky");
        }
});
</script>
<style>
  .sticky {
  	position: fixed;
    z-index: 999;
    top: 0;
    left: 0;
    width: 100%;
    background: red;
  }
</style>

Hi Tuan,

I would like to make 1 section sticky at the top of one page only and with a transparent background (it's a narrow line of text acting as navigation anchor links).

I'm trying to customise the code you gave above, but not having much luck. I put it in Advanced injection code of that page only, right? Is anything required to go in Design/Advanced/CSS to make it transparent?

This is the section ID:

section[data-section-id="5f59e427074004756e44cdd8"]

Thanks so much in advance.

@tuanphan Sorry, I shouldn't have said transparent, I mean 50% opacity white. Thanks
