  • I want to dye all label asterisks Red with vanilla JavaScript.
  • CSS isn't good for this because it would dye both asterisks and colons (`:`) instead just the asterisks:
  • ```css
  • .labelWithColonAndAsterisk:after {
  • content:":*";
  • color:red;
  • }
  • ```
  • So, I need a (vanilla) JavaScript solution.
  • Here is what I have already tried and failed:
  • ```js
  • const labelsWithAnAsterisk = document.querySelectorAll("label");
  • labelsWithAnAsterisk.forEach((element) => {
  • if (element.textContent.indexOf("*") !== -1) {
  • element.textContent.indexOf("*").style.color = "Red";
  • }
  • });
  • ```
  • > Uncaught TypeError: document.qeurySelectorAll is not a function
  • at <anonymous>:1:39
  • I understand that one element can't have two color properties (black for colon and red for asterisk) and this might explain the error.
  • **Anyway, how would you achieve that goal?**

Dye all label asterisks Red with vanilla JavaScript
I want to dye all label asterisks Red with vanilla JavaScript.

CSS isn't good for this because it would dye both asterisks and colons (`:`) instead just the asterisks:

```css
.labelWithColonAndAsterisk:after {
    content:":*"; 
    color:red;
}
```

So, I need a (vanilla) JavaScript solution.

Here is what I have already tried and failed:

```js
const labelsWithAnAsterisk = document.qeurySelectorAll("label");
labelsWithAnAsterisk.forEach((element) => {
    if (element.textContent.indexOf("*") !== -1) {
        element.textContent.indexOf("*").style.color = "Red";
    }
});
```

I understand that one element can't have two color properties (black for colon and red for asterisk) and this might explain the error.

**Anyway, how would you achieve that goal?**
