Image hover always on, on mobile?

Help! I have no coding experience whatsoever. Is there a way to make the caption that comes up when hovering on an image block, always 'on' when viewed on a mobile device?

Sorry if this is a overasked question, or something simple, or something that just isn't possible. Thank you!!

Figured it out! Thanks to: https://stackoverflow.com/questions/2851663/how-do-i-simulate-a-hover-with-a-touch-in-touch-enabled-browsers 

Added this to header code injection: 

<script>
document.addEventListener("touchstart", function(){}, true);
</script>

then added this to custom CSS:

element:hover, element:active {
-webkit-tap-highlight-color: rgba(0,0,0,0);
-webkit-user-select: none;
-webkit-touch-callout: none /*only to disable context menu on long press*/
}
