How can I adjust the opacity of my website header?

Store Design

Hello! I wanted to see if I could make my header the same opacity as it is when hovering. I would also like to make the color of the background of menu items transparent when hovering.

You just need to add below code in your assets/theme.min.css file,

.template-index .header-section:not(.sticky-header) .overlay-header:hover{
background-color: rgba(185, 98, 40, 0.5) !important; 
}

Thank you so much! How can I make the menu items transparent when I hover over them as well? The opacity didn’t apply to them!

I also wanted to see if I can make the caption for the photo right below the header have 50% opacity as well.

Add this code for menu,

.site-nav__dropdown.standard-dropdown li:hover,.site-nav__dropdown.standard-dropdown li:hover>.site-nav__link,.site-nav__dropdown .site-nav__link {
background-color: rgba(185, 98, 40, 0.5) !important; 
}
