To create multicolor text in CSS, you can use the `linear-gradient` property combined with the `-webkit-background-clip: text` and `-webkit-text-fill-color: transparent`.
Here\`s the basic template of how to perform it:
```
.multicolor-text {
/* Add a linear gradient for the text color */
background: -webkit-linear-gradient(left, red, orange, yellow, green, blue, indigo, violet);
/* Use-that gradient as the text color */
-webkit-background-clip: text;
-webkit-text-fill-color: transparent;
/* Add a fallback for browsers that don’t support the above properties */
color: black;
font-size: 30px;
}
```
You can apply this CSS class `multicolor-text` to any text that you want to make it multicolor.
Please note that `-webkit-background-clip: text` and `-webkit-text-fill-color: transparent` are CSS properties specific to WebKit-based browsers (like Chrome and Safari), and may not be supported in all browsers.
