Is there a way to use use text as the background with CSS?

Question

I would like to use dynamic text as background of certain elements in my tag. Because of this, I can use images (dynamic text). How do I do it with just CSS or JavaScript?

Answer 1

Using pure CSS:

(But use this in rare occasions, because HTML method is PREFERRED WAY).

.container{
	position:relative;
}
.container::before{ 
	content:"";
	width: 100%; height: 100%; position: absolute; background: black; opacity: 0.3; z-index: 1;  top: 0;   left: 0;
	background: black;
}
.container::after{ 
	content: "Your Text"; position: absolute; top: 0; left: 0; bottom: 0; right: 0; z-index: 3; overflow: hidden; font-size: 2em; color: red;    text-align: center; text-shadow: 0px 0px 5px black; background: #0a0a0a8c; padding: 5px;
	animation-name: blinking;
	animation-duration: 1s;
	animation-iteration-count: infinite;
	animation-direction: alternate;
}
@keyframes blinking {
	0% {opacity: 0;}
	100% {opacity: 1;}
}
