Hello gianlu

Please use this CSS to Template Options -> Custom Code -> Custom CSS

#sp-header.header-sticky{
    padding: 40px 0px;
}
#sp-header.header-sticky:before {
    background-image: linear-gradient(90deg, #aea6ff 0%, #6973fd 100%);
    transition: 0.3s;
    opacity: 1;
}

Thanks! If i want tu put deep blue instead of current backlight mega menu color like screenshot: https://prnt.sc/2t3SbwBbj3jx it's enough change hex color in your custom css? which is hex code of this color? thanks

Yes, just change the color code in the CSS. The color code is #27285D But what change do you need? If you use the below CSS, then you will get the dark blue color both in sticky header and normal header.

#sp-header {
    background: #27285D;
}
#sp-header:before, #sp-header.header-sticky:before{
    opacity: 0;
}

Hello, the header is fine now in this color. Last thing to do as you see it is to put menu items in white instead of in black as they currently are. How do you change? Thank you

    color: #fff;
}

one last thing. I saw that from mobile the mobile menu symbol as in screenshot is black and I can't change it. is it possible to put this white too? thanks https://prnt.sc/GUD09weuvktF

#offcanvas-toggler>.fa{
    color: #fff;
}

it still does the problem. If you look at the scrolling part of the page, it overlaps the menu from behind. also not where can I change the background of the section where the title is? Indicated with the arrow https://www.screencast.com/t/AEpmGyw2p https://prnt.sc/vOjWmCNC5Hym

Which site are you refering to? I can see blue header.
