header

Click your header, but not the menu.
In the right panel, choose Background, and choose the color you want.
Then at the top of the right panel, choose Header over Block, and Sticky on Scroll.

It worked, but I want my site to only have the header in the desired color when I scroll down, I put the gray color and it was always gray, I want it to be gray only when I scroll down, to highlight the menus, just like the sites I sent as an example
to help you understand, I took a print of my screen, the header of the image 01.png is what I want it to be when I have it at the beginning of the site, the header of the image 02.png
that is gray, I want it to stay when I scroll down the site. follows sites with examples of this functionality in the header: https://genter.com.br/

the header is transparent at the beginning, and when the scroll bar goes down it turns black, in the example site.

I need it.

It should be transparent when at the top of the site.
If it's not, then uncheck the Header over Block and recheck the box and save it again, since sometimes it can be finicky.

Hey,

Can someone help me

How do I make it so that when I scroll down my site through the scroll bar, my header, which is transparent, stays in gray?

I want my header to be transparent only when I have it at the beginning of my site, as soon as I go down I want it to be gray and stand out.

I will provide a site that has this functionality as an example:
https://www.gruposouzalima.com/
https://genter.com.br/

You can set the transparency in the color selection. See screenshot.
