Is there a way to set a max-width using a Pseudo class

I am utilizing a css tooltip that is linked to a span element in the following manner:

<span class="mytooltip" data-mytooltip="Text here. Text here. Text here. Text here. Text here. Text here. Text here. Text here. Text here.">
    Has Tooltip
</span>

The CSS code snippet for this is as follows:

.mytooltip {
  display: inline-block;
  position: relative; 
}
.mytooltip:hover:after {
  content: attr(data-mytooltip);
  display: block;
  margin-top: 0.7rem;
  margin-left: -1rem;
  left: auto;
  bottom: auto;
  padding: .3rem 1rem;
  position: absolute;
  z-index: 98;
  width: 400px; 
}

Within the .mytooltip:hover:after{} width: 400px and 

max-width: 400px; white-space: nowrap;
function as intended. However, the latter part seems redundant because although the pseudo element has the correct width set, the text extends beyond it when it exceeds 400px in length. Is there an alternative method to apply max-width to the pseudo element while ensuring the text wraps inside?

Your input and guidance on this matter would be greatly appreciated.

Answer №1

If you need to create a tooltip with custom text, one way is to manually wrap the tooltip text in your HTML code.

.mytooltip {
  display: inline-block;
  position: relative; 
  margin:15px;
  border: 1px solid red;
  overflow:visible;
}

.mytooltip:hover:after {
  content: attr(data-mytooltip);
  display: table-cell;
  margin-top: 0.7rem;
  margin-left: -1rem;
  left: auto;
  bottom: auto;
  padding: .3rem 1rem;
  position: absolute;
  z-index: 98;
  max-width: 400px; 
  white-space:pre;
  border: 1px solid #000;
  overflow:hidden;
}
<span class="mytooltip" data-mytooltip="Text here. Text here. &#xa;Text here. Text here. Text here. &#xa;Text here. Text here. Text here. Text here. ">
    Has Tooltip
</span>
