I have created an announcement bar but I have a checkbox in case it needed a marquee effect. The problem is that if I add the condition to add the class, it will not put space, the 2 class will just concatenate together. I tried adding a spacebar either way but still not working.
```css
{
"type": "checkbox",
"id": "is_scrolling",
"label": "Scrolling Animation?"
}
The final output will be just like this
