This webpage: https://www.fastcompany.com/90338940/this-is-why-no-one-responds-to-your-email appends a "hover button" only on textselection that moves with the cursor.
I found a CSS hover menu,
<style>.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;
padding: 5px 0;
border-radius: 6px;
position: absolute;
z-index: 1;}
.tooltip:hover .tooltiptext {visibility: visible;}</style>
<div >Hover over me
<span >Tooltip text</span>
</div>
but that is certainly dissimilar from the result achieved here.
So my question is:
How does one achieve such "hover" tip that only appears when text is marked and follows the selection cursor around ?
Edit: This looks like a solution.. How to create tooltip over text selection without wrapping? But once again.. despite shareText.css and shareText.js the popup won't render... odd.
Edit: Popline seems also to go into the direction I'm looking for: http://kenshin54.github.io/popline/ But it seems to be reserved for text editors (?)
