Are there any way to change color of part of a string?-CodePudding

I'am beginner at frontend, and got some design-layout to train. Designer expects that on hover part of string or even letter will change color Example

I thought about CSS 'clip', but doubt

I change the snippet. Play with font-size.

body {
  margin: 0;
  padding: 0;
}

.wrapper {
  position: absolute;
  width: 100vw;
  height: 50vh;
  top: 50%;
  transform: translateY(-50%);
  font-size: 3em;
  font-weight: bold;
  font-family: sans-serif;
  background-color: red;
}

.wrapper1 {
  position: absolute;
  left: 0;
  top: 0;
  width: 100%;
  height: 100%;
  clip-path: inset(0 50% 0 0);
  background-color: blue;
  display: flex;
  justify-content: center;
  align-items: center;
}

.wrapper2 {
  position: absolute;
  left: 0;
  top: 0;
  width: 100%;
  height: 100%;
  clip-path: inset(0 0 0 50%);
  background-color: green;
  display: flex;
  justify-content: center;
  align-items: center;
}

<div >
  <div >Hello World!</div>
  <div >Hello World!</div>
</div>

As G-Cyrillus has pointed out, background-clip with value text can be used, it will 'cut out' characters from the background.

In this simple snippet the background is half white, half black and the blue/white background is supplied in a pseudo before element.

Note that the property requires a -webkit- prefix in some browsers.

* {
  margin: 0;
}

div::before {
  background-image: linear-gradient(to right, blue 0 50%, white 50% 100%);
  content: '';
  width: 100%;
  height: 100%;
  position: absolute;
  top: 0;
  left: 0;
  z-index: -1;
}

div {
  position: relative;
  width: 100vw;
  height: 500px;
  font-size: 50px;
  text-align: center;
  rmix-blend-mode: difference;
  rcolor: white;
  -webkit-background-clip: text;
  background-clip: text;
  color: transparent;
  background-image: linear-gradient(to right, white 0 50%, black 50% 100%);
}

<div>Hello how are you?</div>
