To ensure that all page content (highlighted in red as "Test" in the image) is placed at the top 100% and requires scrolling to view.
The top header (identified in black in the image) should be fixed at the top of the page.
When the content reaches the header, it should start scrolling along with the rest of the content.
(I am unsure where to begin in solving this issue... Is there a way to achieve this without JavaScript?)
Thank you in advance for any assistance provided.
I've discovered a clever technique using a few lines of JavaScript:
var headerFixed = document.getElementById("headerFixed");
var headerClone = document.getElementById("headerClone");
headerClone.innerHTML = headerFixed.innerHTML; // Clone the header content (good for SEO)
function adjustHeaderOpacity(){
var topPos = headerClone.getBoundingClientRect().top; // Keep track of the clone's top position
headerFixed.style.opacity = topPos<0 ? 0 : 1; // Toggle original header opacity
headerClone.style.opacity = topPos<0 ? 1 : 0; // Toggle cloned header opacity
}
adjustHeaderOpacity(); // Execute when DOM is loaded
window.onscroll = adjustHeaderOpacity; // Execute on scroll
window.onresize = adjustHeaderOpacity; // Also execute on resize
The idea behind it:
+-- +----------------+-- (Viewport Top)
| | headerFixed | opacity:1; goes to 0 when the Clone reaches Viewport Top
h +----------------+
e | |
r | |
o +----------------+
| # headerClone | opacity:0; goes to 1 when it reaches Viewport Top
+-- +----------------+-- (Viewport Bottom)
| Content... |

HTML structure:
<div id="hero">
<div id="headerFixed"><h1>Header</h1></div>
<div id="headerClone"></div>
</div>
<div id="content">Website template and content go here</div>
CSS styling:
html, body { height:100%; }
#hero{
height:100%;
}
#headerFixed {
position: fixed;
width: 100%;
}
#headerClone{
position:absolute;
bottom:0;
opacity:0;
width:100%;
}
Hint: if the explanation above is unclear, try adding different background-colors to all elements. It will help visualize what's happening.
