There are plenty of JavaScript-based libraries that show tooltips when you hover your mouse over a certain area of a web page. Some are rather plain, some allow the tooltip
This is my solution for this:

The element recibes a "tooltip-title" attribute with the tooltip text and it is displayed with CSS on hover, I prefer this solution because I don't have to include the tooltip text as a HTML element!
#HTML
<button class="tooltip" tooltip-title="Save">Hover over me</button>
#CSS
body{
padding: 50px;
}
.tooltip {
position: relative;
}
.tooltip:before {
content: attr(tooltip-title);
min-width: 54px;
background-color: #999999;
color: #fff;
font-size: 12px;
border-radius: 4px;
padding: 9px 0;
position: absolute;
top: -42px;
left: 50%;
margin-left: -27px;
visibility: hidden;
opacity: 0;
transition: opacity 0.3s;
}
.tooltip:after {
content: "";
position: absolute;
top: -9px;
left: 50%;
margin-left: -5px;
border-width: 5px;
border-style: solid;
border-color: #999999 transparent transparent;
visibility: hidden;
opacity: 0;
transition: opacity 0.3s;
}
.tooltip:hover:before,
.tooltip:hover:after{
visibility: visible;
opacity: 1;
}
Using the title attribute:
<a href="#" title="Tooltip here">Link</a>
