Text Smoke Effect

[rafterman]

Hello

I am new to CSS and have the following code which creates a smoke fade out animation on mouseover of the site heading text. Is there a way to modify it to eliminate the mouseover trigger and instead have it trigger say 20 seconds after page load?

<style>
.smoke .elementor-widget-container span{
    cursor: default;
    position: relative;
    display: inline-block;
}
.smoke .elementor-widget-container span.active{
    animation: smoke 1s linear;
}
@keyframes smoke{
    50%{
        opacity: 1;
    }
    100%{
        opacity: 0;
        filter: blur(20px);
        transform: translateX(300px) translateY(-300px) rotate(360deg) scale(4);
    }
}
.smoke .elementor-widget-container span.back{
    opacity: 0;
    filter: blur(20px);
    animation: back 1s linear 0.5s;
}
@keyframes back{
    100%{
        opacity: 1;
        filter: blur(0);
    }
}
</style>
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script>
(function($){
$(document).ready(function(){
	    
var heading = $('.smoke .elementor-widget-container').children()

heading.each(function(){
    $(this).html($(this).text().replace(/\S/g, '<span>$&</span>'))  
})

var headingLetter = heading.find('span')

headingLetter.on('mouseover', function(){
    $(this).removeClass('back').addClass('active')
})

headingLetter.on('animationend webkitAnimationEnd oAnimationEnd MSAnimationEnd', function(e){
    if ( $(e.target).hasClass('active')  ){
        $(this).removeClass('active').addClass('back')
    }else{
        $(this).removeClass('back')
    }
})
		
})
}(jQuery))
</script>

Thank you for the help!
