HTML structure is not required for this resource.

Step 2: Add CSS

CSS

Copy
.marquee-css {
  color: #efeeec;
  background-color: #000;
  width: 100%;
  max-width: 42em;
  display: flex;
  position: relative;
  overflow: hidden;
}

.marquee-css__list {
  flex: none;
  align-items: center;
  display: flex;
  position: relative;
}

.marquee-css__item {
  grid-column-gap: 1em;
  grid-row-gap: 1em;
  flex: 0;
  align-items: center;
  padding-top: 1em;
  padding-bottom: 1em;
  padding-right: 1em;
  display: flex;
}

.marquee-css__item-p {
  white-space: nowrap;
  margin-bottom: 0;
  font-size: 1.5em;
  line-height: 1;
}

.marquee-css__item-svg {
  width: 1em;
}

/* CSS Keyframe Animation */
@keyframes translateX { 
	to {
    transform: translateX(-100%);
  }
}

[data-css-marquee-list] {
  animation: translateX 30s linear;
  animation-iteration-count: infinite;
  animation-play-state: paused;
}

Step 2: Add custom Javascript

Custom Javascript in Webflow

In this video, Ilja gives you some guidance about using JavaScript in Webflow:

Step 2: Add Javascript

Step 3: Add Javascript

Javascript

Copy
// Note: The Javascript is optional. Read the documentation below how to use the CSS Only version.

function initCSSMarquee() {
  const pixelsPerSecond = 75; // Set the marquee speed (pixels per second)
  const marquees = document.querySelectorAll('[data-css-marquee]');
  
  // Duplicate each [data-css-marquee-list] element inside its container
  marquees.forEach(marquee => {
    marquee.querySelectorAll('[data-css-marquee-list]').forEach(list => {
      const duplicate = list.cloneNode(true);
      marquee.appendChild(duplicate);
    });
  });

  // Create an IntersectionObserver to check if the marquee container is in view
  const observer = new IntersectionObserver(entries => {
    entries.forEach(entry => {
      entry.target.querySelectorAll('[data-css-marquee-list]').forEach(list => 
        list.style.animationPlayState = entry.isIntersecting ? 'running' : 'paused'
      );
    });
  }, { threshold: 0 });
  
  // Calculate the width and set the animation duration accordingly
  marquees.forEach(marquee => {
    marquee.querySelectorAll('[data-css-marquee-list]').forEach(list => {
      list.style.animationDuration = (list.offsetWidth / pixelsPerSecond) + 's';
      list.style.animationPlayState = 'paused';
    });
    observer.observe(marquee);
  });
}

// Initialize CSS Marquee
document.addEventListener('DOMContentLoaded', function() {
  initCSSMarquee();
});

Step 3: Add custom CSS

Step 2: Add custom CSS

Custom CSS in Webflow

Curious about where to put custom CSS in Webflow? Ilja explains it in the below video:

CSS

Copy
/* CSS Keyframe Animation */
@keyframes translateX { 
  to {
    transform: translateX(-100%);
  }
}

[data-css-marquee-list] {
  animation: translateX 30s linear;
  animation-iteration-count: infinite;
  animation-play-state: paused;
}

Implementation

Attributes

The marquee is targeted via the attribute [data-css-marquee]. The part that is moving on the X axis is targeted by the attribute [data-css-marquee-list].

Speed

The speed of the marquee can be changed in the JavaScript by changing the const pixelPerSecond = 75; variable. Make it higher to go faster.

Functions of the script

  • The CSS animation will be paused when out of view.
  • The width of the [data-css-marquee-list] element is used to calculate the animation duration.
  • The [data-css-marquee-list] is duplicated to create the looping effect.

CSS Only version

Note: For the CSS Only version you don't need the javascript part of this resource. This removes the automatically speed calculation, duplication of the list and the in-view observer.

  • Step 1: Duplicate the [data-css-marquee-list].
  • Step 2: Fine-tune the animation: translateX 30s linear; speed to match the desired result.
  • Step 3: Remove the line animation-play-state: paused; from the CSS.
/* CSS Keyframe Animation */
@keyframes translateX { 
  to {
    transform: translateX(-100%);
  }
}

[data-css-marquee-list] {
  animation: translateX 30s linear; /* Tweak this number in seconds */
  animation-iteration-count: infinite;
  /* Removed: animation-play-state: paused; */
}
