Solution 2 :

Do you Need something like this? I made it by jQuery.

$( document ).ready(function() {
$('.transpar1').find('.engpar1call').hover(function() {
  $('.engpar1').toggleClass( 'fadein' );
});
});
.content {
  color: white;
  font-size: 10vh;
  font-weight: 700;
  display: grid;
  grid-template-columns: repeat(2, 1fr);
  grid-column-gap: 2.5rem;
  grid-template-rows: 1;
  text-align: left;
  color:#000;
}

.engpar1 {
  font-size: 10vh;
  font-weight: 700;
  grid-column: 2;
  grid-row: 1;
  opacity:0; visibility:hidden;
  transition: all .3s ease-in-out;
}

span.engpar1call {
  color: #D93636;
}
.engpar1.fadein{opacity:1;visibility:visible;}

Problem :

Is there a way for me to hover on the span text (“engpar1call”) and have the div called “engpar1” appear on the screen?

In my CSS file, I have my body set up such that the content appears in 2 columns; “transpar1” is always visible on the left, and “engpar1” is supposed to appear when the span “engpar1call” is hovered over. I can’t seem to get the :hover to work, but I am able to style the span.

.content {
  color: white;
  font-size: 10vh;
  font-weight: 700;
  display: grid;
  grid-template-columns: repeat(2, 1fr);
  grid-column-gap: 2.5rem;
  grid-template-rows: 1;
  text-align: left;
}

.engpar1 {
  font-size: 10vh;
  font-weight: 700;
  grid-column: 2;
  grid-row: 1;
  display: none;
  transition-duration: 0.5s;
}

span.engpar1call {
  color: #D93636;
}

I’ve done a bit of searching, and I saw some Javascript that may be of help to me? But I’m not sure if I wrote it correctly because when I tried it, it wasn’t working either.

    var engpar1call = document.getElementsByClassName(".engpar1call");

function showengpar1() {
    var engpar1 = document.getElementsByClassName(".engpar1");

    engpar1.style.display = "inline";
}
engpar1call.addEventListener("mouseover", showengpar1);

getElementsByClassName()

Thanks for clarifying that for me. I also tried it with querySelector() but that wouldn’t work as well. Am I missing something?

Check the snippet, if it helps.
