Creating a Glowing Text Marquee Animation

Web DevelopmentCreating a Glowing Text Marquee Animation


Subtle and visually appealing effects on the web can significantly enhance user experience and engagement. In this tutorial, we’ll guide you through the process of crafting a glowing SVG text coupled with a marquee effect, using only HTML, CSS, and the clip-path property.

You can see this effect in action on the website of Darkroom by Kaploom ® Creative House, the award-winning design membership service.

In this tutorial, we’ll look at how to prepare the design assets in Figma and use the SVGs together with CSS to create the animation. This will be the final result:

So, let’s get started!

Assets

For our assets we’ll need 3 things:

  1. Images we’ll use for the glow effect
  2. Blurred versions of these images to maintain the shape of the glow
  3. Our title in an SVG format

Images

Be sure to export the images in a format that supports transparency (PNG, WEBP, AVIF, etc.)

“Darkroom Core” Box Render
“Darkroom Pro” Box Render

The Blur

Now in Figma, add a “Layer blur” to each image and export them separately. We can export them in a relatively small resolution (50px width) since the browser image rendering will blur our images by default.

Blurring the assets in Figma

Preparing the SVG title

Our SVG title will be used in a marquee effect, which we call a “Rail”. In this case, we’ll need at least one duplicate of the title so it covers the whole screen at all times.

Don’t worry about the colors at this step, since we’ll apply them though code and by using our previously exported blurred images.

“DARKROOM” title frame in Figma

It’s important to make sure the spacing between the title and the duplicate matches the end frame spacing so that later on, we get a smooth marquee effect without any unexpected jumps.

“DARKROOM” title spacing in Figma

When exporting the SVG from Figma, apply a border to the title and check the “Simplify Stroke” box under export settings.

Converting the Path

Now that we have our SVG we need to convert the path from userSpaceOnUse to objectBoundingBox. We can do that using this online converter.

<svg width="1137" height="104" viewBox="0 0 1137 104" fill="none" xmlns="http://www.w3.org/2000/svg">
    <path d="M13.2057 88.8793V89.3793H13.7057H30.9417C40.7369 89.3793 48.6776 81.4387..." fill="white" stroke="white"/>
</svg>

Here’s how our objectBoundingBox path should look:

M0.012,0.867 V0.872 H0.012 H0.027 C0.036,0.872,0.043,0.794,0.043,0.699 V0.314 C0.043,0.218,0.036,0.141,0.027,0.141 H0.012 H0.012 V0.146...

Creating the Rail

For this component, we’ll need the blurred image assets we just exported and our objectBoundingBox path which we’ll use for our SVG mask.

Here is the basic structure of our Rail component:

<div class="rail">
	<div class="rail_container">
	  <div class="rail_clip">
		<div class="rail_color">
		  <div class="rail_gradients">

			 /* Blurred images go here */
			  <img
				src="img/gradient-core.png"
				width="50"
				height="50"
				alt="Core Gradient"
				class="rail_gradient -core"
			  />
			  <img
				src="img/gradient-pro.png"
				width="50"
				height="50"
				alt="Pro Gradient"
				class="rail_gradient -pro"
			  />

		  </div>
		</div>
	  </div>

	   /* Rail sizing used for precise aspect ratio */
	  <svg
		width="1137"
		height="104"
		viewBox="0 0 1137 104"
		fill="none"
		xmlns="http://www.w3.org/2000/svg"
		class="rail_sizing"
	  ></svg>

	  /* SVG Mask */
	  <svg class="rail_mask">
		<clipPath id="contentTitle" clipPathUnits="objectBoundingBox">
		  <path

		</clipPath>
	  </svg>

	</div>
</div>

Mask, Sizing and Animation

For the Rail mask, we’ll use the CSS clip-path property with and ID and apply it to the .rail_clip class.

.rail_clip {
    position: absolute;
    inset: 0;
    display: flex;
    justify-content: center;
    align-items: center;
    width: 100%;
    height: 100%;
    -webkit-clip-path: url("#contentTitle");
    clip-path: url("#contentTitle");
}

To make sure the <strong>clip-path</strong> keeps the correct aspect ratio we added <strong>.rail_sizing</strong> with its position set to relative. It will also determine the overall size of our Rail component.

.rail_sizing {
	position: relative;
	opacity: 0;
	height: auto;
	width: 200vw;
}

For the marquee effect, use a simple CSS animation that loops infinitely. The speed will depend on your SVG’s width and the length of the CSS animation.

.rail_clip {
  animation: clip-anim 20s linear infinite;
}

@keyframes clip-anim {
	from {
		transform: translateX(0%);
   }
	to {
		transform: translateX(-50%);
   }
}

Color and Gradients

Now for the fun part – colors!

First, apply a background color to the .rail_color class to ensure the title is visible even without gradients.

.rail_color {
	position: absolute;
	inset: 0;
	height: 100%;
	width: 100%;
	background-color: #0c0c0e;
}

Now since we’re animating the whole .rail_clip, with .rail_color being its child element, you’ll notice the background color is animating out of view… We want it to stand still!

So what need to do is animate the .rail_color in the opposite direction like so:

.rail_color {
	animation: color-anim 20s linear infinite;
}

@keyframes color-anim {
    from {
        transform: translateX(0%);
   }
    to {
        transform: translateX(50%);
   }
}

With that out of the way, we can add our blurred images inside the .rail_color div and align them to where we need them to be!

Accessibility

Last, but certainly not least… let’s add the title text for screen readers at the top of our Rail component and style it accordingly!

<div class="rail">
	<div class="screen-reader-text">DARKROOM</div>
	<div class="rail_container">
	  ...
	</div>
</div>
.screen-reader-text {
    position: absolute !important;
    overflow: hidden;
    clip: rect(0 0 0 0);
    margin: 0;
    padding: 0;
    width: 1px;
    height: 1px;
    border: 0;
}

Finishing up

All that’s left to do now is add our main image assets over the Rail component, align them with our masked gradients, and add a little floating animation to each of the boxes.

@keyframes float-core {
    from {
        transform: translateY(0%);
   }
    to {
        transform: translateY(5%);
   }
}

@keyframes float-pro {
    from {
        transform: translateY(4%);
   }
    to {
        transform: translateY(0%);
   }
}

For an even better blending with our Rail component, we added a slight glow behind each box using the same blurred images with no clip-mask this time, but with the opacity turned way down.

It’s subtle but it adds a lot!
