How can I apply a continuous gradient to animated split text in React?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I'm trying to apply a continuous linear gradient to words animated by the SplitText component, but the gradient is affecting individual letters rather than the whole word. I've attempted several modifications to the SplitText component, its CSS, and JS with no success.

I got the SplitText code from: https://www.reactbits.dev/text-animations/split-text

Below is the relevant code:

SplitText

JAVASCRIPT
import { useSprings, animated } from '@react-spring/web';
import { useEffect, useRef, useState } from 'react';

const SplitText = ({
  text = '',
  className = '',
  delay = 100,
  animationFrom = { opacity: 0, transform: 'translate3d(0,40px,0)' },
  animationTo = { opacity: 1, transform: 'translate3d(0,0,0)' },
  easing = 'easeOutCubic',
  threshold = 0.1,
  rootMargin = '-100px',
  onLetterAnimationComplete,

}) => {
  const words = text.split(' ').map((word) => word.split(''));
  const letters = words.flat();
  const [inView, setInView] = useState(false);
  const ref = useRef();
  const animatedCount = useRef(0);

  useEffect(() => {
    const observer = new IntersectionObserver(
      ([entry]) => {
        if (entry.isIntersecting) {
          setInView(true);
          observer.unobserve(ref.current);
        }
      },
      { threshold, rootMargin }
    );

    observer.observe(ref.current);

    return () => observer.disconnect();
  }, [threshold, rootMargin]);

  const springs = useSprings(
    letters.length,
    letters.map((_, i) => ({
      from: animationFrom,
      to: inView
        ? async (next) => {
            await next(animationTo);
            animatedCount.current += 1;
            if (animatedCount.current === letters.length && onLetterAnimationComplete) {
              onLetterAnimationComplete();
            }
          }
        : animationFrom,
      delay: i * delay,
      config: { easing },
    }))
  );

  return (
    <div
      ref={ref}
      className={`split-parent ${className}`}
      style={{
        background: "linear-gradient(90deg, #27093B 0%, #B242FF 40.5%, #B242FF 59%, #27093B 100%)",
        WebkitBackgroundClip: "text",
        color: "transparent"
      }}
    >
      {words.map((word, wordIndex) => (
        <span
          key={wordIndex}
        >
          {word.map((letter, letterIndex) => {
            const index = words
              .slice(0, wordIndex)
              .reduce((acc, w) => acc + w.length, 0) + letterIndex;

            return (
              <animated.span
                key={index}
                style={{
                  ...springs[index],
                  display: 'inline-block',
                  willChange: 'transform, opacity',
                }}
              >
                {letter}
              </animated.span>
            );
          })}
          <span style={{ display: 'inline-block', width: '0.3em' }}>&nbsp;</span>
        </span>
      ))}
    </div>
  );
};

export default SplitText;

CSS

CSS
.hero .marketing {
    font-family: 'Urbanist', sans-serif;
    font-weight: bolder;
    font-size: 198px;
    font-weight: 900;
    left: 0;
    letter-spacing: 0;
    line-height: normal;
    text-align: center;
    top: 0;
    padding-top: 127px;
    z-index: 1;
    background: linear-gradient(90deg, #27093B 0%, #B242FF 40.5%, #B242FF 59%, #27093B 100%);
    background-clip: text;
  }
   
  .hero .digital {
    font-family: 'Urbanist', sans-serif;
    font-weight: bolder;
    font-size: 198px;
    font-weight: 900;
    left: 0;
    letter-spacing: 0;
    line-height: normal;
    text-align: center;
    top: 0;
    margin-top: -85px;
  }

JAVASCRIPT
 <SplitText
          text="DIGITAL"
          className="digital"
          delay={150}
          animationFrom={{ opacity: 0, transform: 'translate3d(0,50px,0)' }}
          animationTo={{ opacity: 1, transform: 'translate3d(0,0,0)' }}
          easing="easeOutCubic"
          threshold={0.2}
          rootMargin="-50px"
        />
        <SplitText
          text="MARKETING"
          className="marketing"
          delay={150}
          animationFrom={{ opacity: 0, transform: 'translate3d(0,50px,0)' }}
          animationTo={{ opacity: 1, transform: 'translate3d(0,0,0)' }}
          easing="easeOutCubic"
          threshold={0.2}
          rootMargin="-50px"
        />

I'm looking for a solution that applies the gradient to whole words instead of each animated letter. Any help or suggestions would be appreciated!

The issue is that by splitting the text into individual animated letter elements (each having its own display, etc.), the CSS gradient is effectively “reset” on every letter. For a continuous gradient across an entire word, the gradient needs to be applied at a container level that wraps the whole word rather than on each letter.

Below are two common approaches to resolve this:

1. Wrap Each Word in a Gradient Container

Instead of applying the gradient on the overall parent container (which gets inherited by each letter), wrap each word in its own span (or similar element) that has the gradient background and text clipping applied. This way each word gets the continuous gradient while you can still animate its letters. For example, update the render code in your SplitText component like so:

JSX
return (
  <div ref={ref} className={`split-parent ${className}`}>
    {words.map((word, wordIndex) => (
      // Apply the gradient styling on the word wrapper
      <span
        key={wordIndex}
        style={{
          background: "linear-gradient(90deg, #27093B 0%, #B242FF 40.5%, #B242FF 59%, #27093B 100%)",
          WebkitBackgroundClip: "text",
          color: "transparent",
          display: "inline-block",
        }}
      >
        {word.map((letter, letterIndex) => {
          const index = words
            .slice(0, wordIndex)
            .reduce((acc, w) => acc + w.length, 0) + letterIndex;
          return (
            <animated.span
              key={index}
              style={{
                ...springs[index],
                // Change animated letter display to inline.
                // You might test whether "inline-block" is needed for your animation.
                display: 'inline',
                willChange: 'transform, opacity',
              }}
            >
              {letter}
            </animated.span>
          );
        })}
        {/* Spacer between words */}
        <span style={{ display: 'inline-block', width: '0.3em' }}>&nbsp;</span>
      </span>
    ))}
  </div>
);

What This Does:
• The word-level wrapping span uses the gradient and clipping so the entire word shows the gradient continuously.
• The individual letter spans are now inside this container, so while they animate independently (using transform/opacity), they do not “reset” the gradient effect.

2. Animate Without Breaking the Gradient Flow

If splitting into letters is needed for the animation but you want to keep a single gradient, another approach is to let the parent container hold the gradient and have each letter’s element be transparent without setting its own background. For this to work, ensure that:

The parent (e.g., the word wrapper) holds the gradient background and background-clip: text.
The animated letter spans do not override the text color (i.e. no background or color is applied on them).
You may need to adjust the display property on the letter spans from inline-block to inline (or use a technique like CSS transforms on inline elements) so that the parent's background can show through continuously.

For example, you might try removing the inline gradient style from each animated span and instead set it only on a word wrapper as shown above.

Final Notes

Animation Considerations: Changing from inline-block to inline might affect how transforms are rendered. Test your animations and adjust as needed (for example, consider wrapping each letter in an extra container if both inline display and a transform are required).
CSS Clipping: Remember that background-clip: text works when the element’s text fills the element. By applying it to the word wrapper, all child letters become part of the same “text image.”

Using one of these approaches should let you have a continuous gradient over the whole word while still animating the split letters independently.
