Edit This Code:
<!DOCTYPE html>
<html>
<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;
    border-radius: 6px;
    padding: 5px 0;

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

.tooltip:hover .tooltiptext {
    visibility: visible;
}
</style>
<body style="text-align:center;">

<p>Move the mouse over the text below:</p>

<div class="tooltip">Hover over me
  <span class="tooltiptext">Tooltip text</span>
</div>

<p>Note that the position of the tooltip text isn't very good. Go back to the tutorial and continue reading on how to position the tooltip in an desirable way.</p>
