Can my tooltips be adapted for touch screen?

Question

I've worked on the tool tips for my adverts which bust jargon quite a lot - they show with a simple mouse over. Obviously they don't work on touch interfaces.

I'm limited to ideally pure HTML5 and CSS3, definitely no jquery, ideally no javascript. I've tried changing (or rather adding) :active to the :hover class but nothing happens on a touch screen at all.

Current HTML and CSS is

.tiptext {
  cursor: help;
  color: black;
  font-family: 'ProximaNova', 'Helvetica Neue', Helvetica, Arial, 'Lucida Grande', sans-serif;
  font-weight: 600 !important;
  border-bottom: 1px solid #ebebeb;
  box-shadow: inset 0 -5px 0 #ebebeb;
  -webkit-transition: background .15s cubic-bezier(.33, .66, .66, 1);
  transition: background .15s cubic-bezier(.33, .66, .66, 1);
  text-decoration: none;
  font-size: 14px;
  line-height: 172%;
  -webkit-animation-name: link-helpoff;
  -webkit-animation-duration: 1s;
  animation-name: link-helpoff;
  animation-duration: 1s;
  -webkit-animation-fill-mode: both;
  animation-fill-mode: both;
  transition-delay: 0.4s;
}
.tiptext::after {
  content: "";
  position: fixed;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  pointer-events: none;
  color: transparent;
  background-color: transparent;
  transition: background-color 0.5s linear;
}
.tiptext:hover::after {
  background-color: rgba(255, 255, 255, 0.6);
}
.description {
  border: 1px solid #e3e3e3;
  background: white;
  width: auto;
  max-width: 275px;
  height: auto;
  padding: 10px;
  font-family: 'ProximaNova', 'Helvetica Neue', Helvetica, Arial, 'Lucida Grande', sans-serif;
  font-weight: 300;
  color: rgb(39, 44, 45);
  font-size: 13px;
  z-index: 500;
  position: absolute;
  margin-left: 50px;
  margin-top: 20px;
  cursor: default;
  display: inline-block;
}
.tiptext > .description {
  visibility: hidden;
  opacity: 0;
  transition: visibility 0s linear 0.4s, opacity 0.4s linear;
}
.tiptext:hover > .description {
  visibility: visible;
  opacity: 1;
  transition-delay: 0s;
  -webkit-transition: opacity 0.2s ease-in;
  -moz-transition: opacity 0.2s ease-in;
  -ms-transition: opacity 0.2s ease-in;
  -o-transition: opacity 0.2s ease-in;
  transition: opacity 0.2s ease-in;
}
.tiptext:hover {
  color: black;
  -webkit-animation-name: link-help;
  -webkit-animation-duration: 0.6s;
  animation-name: link-help;
  animation-duration: 0.6s;
  -webkit-animation-fill-mode: both;
  animation-fill-mode: both;
  transition-delay: 0s;
}

<span class="tiptext">
  <span class="description" style="text-align:center;">You can read more about the topic in this pop up box</span>
  Mouse over me to learn more.
</span>

There some animations and trickery going on in the CSS (and I haven't included the link-help animation but you get the idea) basically the box fades in and out when you mouse over it - and there is also a full screen white background that fades in with a little opaque to bring the moused over box into focus - its no big deal if this doesn't happen on touch screen devices.

I suspect there might need to be substantial changes to get the same pop up box on press on touch screen devices.

Yes, there is a way.

First: add the attribute "ontouchstart" to your button. Second: add a style for :active, :focus, and :hover.

I have tested this on iOS and it works. (Haven't tried it out with Android).

div {
  display: none;
}
button {
  width: 200px;
  height: 50px;
  border: 1px solid red;
  display: inline-block;
  
}
button:active,
button:focus,
button: hover {
  background-color: blue;
}
button:active + div,
button:focus + div,
button:hover + div {
  display: block;
}

<p>Hello</p>
<button ontouchstart>Activate</button>
