To slow down a CSS infinite ticker when hovering, you can utilize CSS animations with the transition property. Here’s an overview of how this can be done:
Create the Ticker Animation: First, create a CSS animation to scroll your text infinitely. This involves defining a keyframes animation where your content moves from its initial position to the final off-screen position, creating the ticker effect.

css
@keyframes ticker {
0% { transform: translateX(100%); }
100% { transform: translateX(-100%); }
}

.ticker {
width: 100%;
overflow: hidden;
white-space: nowrap;
box-sizing: border-box;
}

.ticker-content {
display: inline-block;
padding: 0 100%;
animation: ticker linear infinite 10s;
}

In this example, .ticker-content has a horizontal scrolling animation that lasts 10 seconds per cycle.
Modify Speed on Hover: To slow down the animation on hover, use the animation-play-state property or adjust the animation speed directly. Here, we’ll slow down the animation by modifying the animation duration itself on hover.

css
.ticker-content:hover {
animation-play-state: paused; / Alternatively, this can be used to pause /
animation: ticker linear infinite 30s; / Slows down the animation to 30 seconds on hover /
transition: animation-duration 0.5s; / Smooth transition for speed change /
}

The above CSS will apply a new animation duration when the .ticker-content is hovered over, effectively slowing down the content’s scrolling speed.
Ensure Smooth Interactions: To ensure a smooth hover interaction, use CSS transitions. The transition property allows for a smooth transition effect when the animation duration changes, enhancing user experience.

By setting up your CSS like this, you create a seamless effect where the ticker slows down as soon as a user hovers over it, and returns to its original speed once the hover ends, providing a dynamic interaction experience.
