Set top tooltip with CSS
To set a top tooltip with CSS, you position the tooltip above the element using the bottom property along with position: absolute. The tooltip appears above the trigger element when hovered.
Syntax
.tooltip .tooltip-text {
position: absolute;
bottom: 100%;
visibility: hidden;
}
.tooltip:hover .tooltip-text {
visibility: visible;
}
Example
The following example creates a tooltip that appears at the top when you hover over the text −
<!DOCTYPE html>
<html>
<head>
<style>
.mytooltip {
position: relative;
display: inline-block;
margin-top: 60px;
background-color: #f0f0f0;
padding: 10px 15px;
border: 1px solid #ccc;
cursor: pointer;
}
.mytooltip .mytext {
visibility: hidden;
width: 140px;
background-color: #333;
color: white;
text-align: center;
border-radius: 6px;
padding: 8px;
position: absolute;
z-index: 1;
bottom: 100%;
left: 50%;
margin-left: -70px;
margin-bottom: 5px;
}
.mytooltip:hover .mytext {

}
/* Optional: Add arrow pointing down */
.mytooltip .mytext::after {
content: "";
position: absolute;
top: 100%;
left: 50%;
margin-left: -5px;
border-width: 5px;
border-style: solid;
border-color: #333 transparent transparent transparent;
}
</style>
</head>

</div>
</body>

A gray box with text "Hover over me" appears. When you hover over it, a dark tooltip with white text "This tooltip appears on top!" shows above the box with a small arrow pointing down.
