How To Create A Transparent Overlay Header Over A Fullscreen Hero Section In Helix Ultimate
sZone
Hi, I'm using Helix Ultimate 2.2.6 on Joomla 6 and I'd like to implement a transparent overlay header. What I want to achieve:
On page load: the header (logo + navigation) is fully transparent and visually overlaps the content below it – so the content starts at the very top of the viewport, directly behind the header On scroll: the header becomes a solid or semi-transparent sticky bar that stays fixed at the top
My question: What is the correct and recommended way to implement this in Helix Ultimate 2.2.x? Is there a built-in option, a specific predefined header style that supports this, or does it require custom CSS/JS? A working example or code snippet would be very helpful. Thank you!

Accepted AnswerHi,
Thanks for contacting us. Header is part of the Helix template. Commercial templates have their own unique features, so in some there are transparent headers.
Basic Helix Ultimate does not have this feature out of the box, so you need to use CSS to make it.
Explanation: Let's imagine for clarity that Body has a blue background.
Header has position: relative; by default. Therefore, when you make its color transparent, you start to see the color of Body and it seems to you that nothing happens (as in reality Body has white bg color ).
In order to achieve transparency, you need to pull the header from the flow of elements. Then, everything that is below is shifted under Header. This can be done using position: absolute;.
For example you can use this CSS in your custom.css file
#sp-header {
position: absolute;
background: rgba(0,0,0,0.3);
}-Regards.
