How to add scrolling text

Something like the one in the example

https://extendthemes.com/scrolling-text/

I tried the following in the custom CSS but it is not working.

.menu-header::after{
font-size: 3em;
color: red;
position: absolute:
content: “My scrolling text here”;
}

I am using a child theme

I added the css in the Custom CSS in the Theme Options. Do I need to add this in the style.css in the child theme?

It would be much easier to add the marquee tag like this in html. But not sure
<marquee style=”font-size: 20px; color: red;”> My scrolling text </marquee>
