text won't show up when hovering-CodePudding

For my website I want to use a hover function that shows text once hovering over an imgae with the mouse. Because I want to implement multiple pictures I used a table whichin each td represents one image.

My problem is that once hovering, the overlay shows but there is no text displayed

I'm a complete beginner in html and css, so if there is anything else I can do different and more efficiently, feel free to let me know.

.container {
  position: relative;
  width: 50%;
}

.moon {
  display: block;
  width: 100%;
  height: auto;
}

.overlay {
  position: relative;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  height: 300px;
  width: 300px;
  opacity: 0;
  transition: .5s ease;
  background-color: white;
}

.container:hover {
  opacity: 0.6;
  filter: alpha(opacity=10);
}

.text {
  color: blue;
  font-size: 20px;
  position: absolute;
  top: 50%;
  left: 50%;
  -webkit-transform: translate(-50%, -50%);
  -ms-transform: translate(-50%, -50%);
  transform: translate(-50%, -50%);
  text-align: center;
}

.mr {
  position: relative;
  float: left;
  width: 300px;
  padding-left: 40px;
}

.mr:hover {
  opacity: 0.6;
  filter: alpha(opacity=10);
}

.plant {
  position: relative;
  width: 300px;
  padding-left: 40px;
  padding-right: 120px;
  float: left;
}

.plant:hover {
  opacity: 0.6;
  filter: alpha(opacity=10);
}

.karteone {
  position: relative;
  width: 300px;
  padding-top: 40px;
}

.karteone:hover {
  opacity: 0.6;
  filter: alpha(opacity=10);
}

.kartetwo {
  position: relative;
  float: left;
  width: 300px;
  padding-top: 39.5px;
  padding-left: 40px;
}

.kartetwo:hover {
  opacity: 0.6;
  filter: alpha(opacity=10);
}

You could use tooltip class from css. This will display the tooltip text while hovering.

.tooltip {
  position: relative;
  display: inline-block;
  border-bottom: 1px dotted black;
}

.tooltip .tooltiptext {
  visibility: hidden;
  width: 120px;
  background-color: black;
  color: #fff;
  text-align: center;
  border-radius: 6px;
  padding: 5px 0;

  /* Position the tooltip */
  position: absolute;
  z-index: 1;
}

.tooltip:hover .tooltiptext {
  visibility: visible;

<div >Hover over me
  <span >Tooltip text</span>
</div>

If you want the .overlay to appear on .container:hover, then the code sould be: .container:hover .overlay, like so:

.container {
  position: relative;
  width: 50%;
}

.moon {
  display: block;
  width: 100%;
  height: auto;
}

.overlay {
  position: relative;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  height: 300px;
  width: 300px;
  opacity: 0;
  transition: .5s ease;
  background-color: white;
}

.container:hover .overlay{
  opacity: 0.6;
  filter: alpha(opacity=10);
}

.text {
  color: blue;
  font-size: 20px;
  position: absolute;
  top: 50%;
  left: 50%;
  -webkit-transform: translate(-50%, -50%);
  -ms-transform: translate(-50%, -50%);
  transform: translate(-50%, -50%);
  text-align: center;
}

.mr {
  position: relative;
  float: left;
  width: 300px;
  padding-left: 40px;
}

.mr:hover {
  opacity: 0.6;
  filter: alpha(opacity=10);
}

.plant {
  position: relative;
  width: 300px;
  padding-left: 40px;
  padding-right: 120px;
  float: left;
}

.plant:hover {
  opacity: 0.6;
  filter: alpha(opacity=10);
}

.karteone {
  position: relative;
  width: 300px;
  padding-top: 40px;
}

.karteone:hover {
  opacity: 0.6;
  filter: alpha(opacity=10);
}

.kartetwo {
  position: relative;
  float: left;
  width: 300px;
  padding-top: 39.5px;
  padding-left: 40px;
}

.kartetwo:hover {
  opacity: 0.6;
  filter: alpha(opacity=10);
}

          </td>
          <td><img  src="images/mr.me.png" alt="mr"></td>
          <td><img  src="images/plant planet.png" alt="plant"></td>
        </tr>
      </table>

Or apply before and/or after in the CSS, like this:

.container {
  position: relative;
  width: 50%;
}

.moon {
  display: block;
  width: 100%;
  height: auto;
}

.overlay {
  position: relative;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  height: 300px;
  width: 300px;
  opacity: 0;
  transition: .5s ease;
  background-color: white;
}

.container:hover {
  opacity: 0.6;
  filter: alpha(opacity=10);
}

.text {
  color: blue;
  font-size: 20px;
  position: absolute;
  top: 50%;
  left: 50%;
  -webkit-transform: translate(-50%, -50%);
  -ms-transform: translate(-50%, -50%);
  transform: translate(-50%, -50%);
  text-align: center;
}

.mr {
  position: relative;
  float: left;
  width: 300px;
  padding-left: 40px;
}

.mr:hover {
  opacity: 0.6;
  filter: alpha(opacity=10);
}

.plant {
  position: relative;
  width: 300px;
  padding-left: 40px;
  padding-right: 120px;
  float: left;
}

.plant:hover {
  opacity: 0.6;
  filter: alpha(opacity=10);
}

.karteone {
  position: relative;
  width: 300px;

}
