Tips for creating a dynamic scrolling effect with a background color that transitions smoothly from left to right

This is the code I have written:

      <div class="titlediv" style='background:linear-gradient(90deg, #cc2900 79%, #b3b3b3 21%);'>
        <h2> Hello
        </div>
        
        <p> My name is Josh and I need Help </p>
        <p> My name is Josh and I need Help </p>
        (repeated lines omitted for brevity)
        <p> My name is Josh and I need Help </p>
        
      <div class="titlediv" style='background:linear-gradient(90deg, #cc2900 79%, #b3b3b3 21%);'>
        <h2> Hello
        </div>

In this code snippet, there are two <h2> tags with background colors.

I am looking to create a left-to-right fill animation effect for the background color when it appears on the screen.

🎨 Creating CSS Gradient Animations

When it comes to animating gradients, linear-gradients are not inherently animatable.

A workaround is to set the initial gradient as the background of an element, then overlay another gradient using a separate element (or pseudo-element) with appropriate z-index values. Utilize other animatable properties like opacity or positional properties such as position, left, top, and width to simulate the gradient animation effect.
