The sticky position is malfunctioning even when there is no parent element with the overflow hidden property

// observer for feature section
let featuresSection = document.querySelector('#featuresSection');

let callbackFeature = (items) => {
    items.forEach((item) => {
        if (item.isIntersecting) {
            item.target.classList.add("in-page");

        } else {

            item.target.classList.remove("in-page");

        }
    });
}
let observerFeature = new IntersectionObserver(callbackFeature, {
    threshold: 0.3
});
observerFeature.observe(featuresSection);
.features-section.in-page {
    position: -webkit-sticky;
    position: -moz-sticky;
    position: -ms-sticky;
    position: -o-sticky;

    position: sticky !important;
    top: 0 !important;
    background-color: red;
    display: block;
  }
  
   .features-img {

    transition: all 0.5s cubic-bezier(0.215, 0.61, 0.355, 1);

What could be the reasons why a sticky element fails to work, other than:

  • Having a parent element with overflow:hidden
  • Omitting to specify the top position to stick to
  • The sticky element being within a flexbox or grid
  • Lack of browser support for the sticky property

Despite the fact that my element doesn't exhibit any of those complications, I have meticulously examined for an overflow:hidden in the CSS both using CTRL+F and a script that verifies it in the console. Yet it fails to adhere to the top of the page. Any assistance would be appreciated.

This is the CSS applied to my section: The red background is utilized for testing purposes and functions correctly, but the sticky property does not.

.features-section.in-page {
    position: -webkit-sticky;
    position: -moz-sticky;
    position: -ms-sticky;
    position: -o-sticky;

    position: sticky !important;
    top: 0 !important;
    background-color: red;
    display: block;
  }

Additionally, this is the structure of my section:

This is the JS code employing an Intersection Observer to assign the position sticky and a red background color for debugging purposes:

// observer for feature section
let featuresSection = document.querySelector('#featuresSection');

let callbackFeature = (items) => {
    items.forEach((item) => {
        if (item.isIntersecting) {
            item.target.classList.add("in-page");

        } else {

            item.target.classList.remove("in-page");

        }
    });
}
let observerFeature = new IntersectionObserver(callbackFeature, {
    threshold: 0.3
});
observerFeature.observe(featuresSection);

Answer №1

Sticky elements are designed to stick within their parent element without overflowing once they reach the bottom of the closest positioned parent. If another sticky element intersects with it, it will move accordingly.

An example showcasing how this behavior works:

// observer for feature section
let featuresSection = document.querySelector('#featuresSection');

let callbackFeature = (items) => {
  items.forEach((item) => {
    if (item.isIntersecting) {
      item.target.classList.add("in-page");

    } else {

      item.target.classList.remove("in-page");

    }
  });
}
let observerFeature = new IntersectionObserver(callbackFeature, {
  threshold: 0.2
});
observerFeature.observe(featuresSection);
.features-section.in-page {
  position: sticky;
  top: 0;
  background-color: red;
}

.features-img {
  width: 100%;
  object-fit: contain;
  transition: all 0.5s cubic-bezier(0.215, 0.61, 0.355, 1);
}

To enhance user experience, only stick the titles

Let's implement this and witness its functionality ;)

// observer for feature section
let featuresSection = document.querySelector('#featuresSection');

let callbackFeature = (items) => {
  items.forEach((item) => {
    if (item.isIntersecting) {
      item.target.classList.add("in-page");

    } else {

      item.target.classList.remove("in-page");

    }
  });
}
let observerFeature = new IntersectionObserver(callbackFeature, {
  threshold: 0.3
});
observerFeature.observe(featuresSection);
.features-section.in-page {
  position: sticky;
  z-index: 1;
  top: 0;
  background-color: red;
}

.features-img {
  width: 100%;
  object-fit: contain;
  transition: all 0.5s cubic-bezier(0.215, 0.61, 0.355, 1);

      </div>
    </section>

Note: Prefixes are no longer required for modern browsers, !important is unnecessary, but z-index may be beneficial :).

Answer №2

Perhaps this isn't exactly what you were looking for, but the intersection observer is not necessary (though I do appreciate the use of these newer DOM methods).... If your goal is simply to make the header elements stick to the top of the page while scrolling, then applying position-sticky to them specifically is the way to go - rather than the entire section.

To simplify things, I grouped the h2 and h3 in a div and applied position sticky to that container. It's important to note that setting the z-index is crucial to ensure that the content scrolls underneath the fixed header.

I took out the intersection observer to showcase the new div structure and style adjustments.

.header-wrapper {
    position: -webkit-sticky;
    position: -moz-sticky;
    position: -ms-sticky;
    position: -o-sticky;

    position: sticky;
    top: 0;
    background-color: red;
    display: block;
    z-index: 99
  }
  
   .features-img {
   width:100%
    object-fit: contain;
    transition: all 0.5s cubic-bezier(0.215, 0.61, 0.355, 1);
  }
