Last Updated : 09 Jul, 2020

Link tooltips are a great way to display extra information when an element or link is hovered on. There are several ways to do this.

Using CSS and jQuery: The mousenter and mouseleave events are used in jQuery to perform this operation.

<!DOCTYPE html>
<html>

<head>
    <style>
        .tooltip {
            display: none;
            position: absolute !important;
            width: 200px;
            padding: 10px;
            margin: 0 0 3px 0;
            color: #fff;
            z-index: 1;
            font-size: 50px;
            text-decoration: none;
            text-align: center;
        }

        .tooltip:after {
            position: absolute !important;
            bottom: -14px;
            z-index: 1;
        }

        .tooltip:before {
            content: "";
            position: absolute !important;
            bottom: -14px;
            z-index: 100;
        }
    </style>

</head>

<body>
    <a href="#" class="link" title="Hello world!"
            class="tooltip_link left">
        Hover over me!
    </a>

    <script>
        $("a").mouseenter(function (e) {
            var $x = e.pageX - this.offsetLeft;
            var $tooltip_text = $(this).attr("title");

            $(this).append('<div class="tooltip">' 
                    + $tooltip_text + '</div>');
            $("a > div.tooltip.").fadeIn(300);

        });

        $("a").mouseleave(function () {
            $("a > div.tooltip.").fadeOut(300)
                    .delay(300)(function () {
                $(this).remove();
            });
        });
    </script>
</body>

</html>

Output:

After hovering mouse on "Hover over me!" , the output is

Hello world!

Using jQuery UI: The tooltip widget of jQuery UI helps to customize tooltips. The tooltip() method is used to add tooltip to any element.

            margin-top: 3rem;
            text-decoration: none;
            color: green;
