How to Create Tooltips with Bootstrap

by Vincy. Last modified on July 12th, 2022.

In HTML, we can add a title attribute for an element. The text specified in this attribute is shown as a tooltip on the mouse over event. In this tutorial, we are going to create tooltips by using Bootstrap and it has good additional features over the standard tooltip.

We initialize the Bootstrap tooltip by referring the element id selector with which the tooltip function should be triggered. In a previous tutorial, we have seen how to show form validation messages using the tooltip.

Bootstrap Tooltip library contains several options to customize the tooltip style, speed, content and more. We can override the default options by setting them while calling the tooltip function.

In this example, I set the delay time for the animation effect and the title options with the JavaScript. If there is no title attribute specified or it is empty then the title specified in the JavaScript will be shown in the tooltip.

HTML Elements Triggers Tooltip

The code shows the HTML elements with which the tooltip library function is called on the mouse over event. It shows four DIV elements that trigger tooltip on hover by specifying the tooltip placement location by using data attribute.

<div class="tooltip-buttons">
	<div class="btnTooltip" data-placement="top" title="Tooltip showing in the top position.">Top</div>
	<div class="btnTooltip" data-placement="right">Right</div>
	<div class="btnTooltip" data-placement="bottom">Bottom</div>
	<div class="btnTooltip" data-placement="left" title="Tooltip showing in the left position.">Left</div>

jQuery Script to call Bootstrap Tooltip

The following jQuery code shows how to trigger tooltip by specifying options as its arguments. I specify delay and default title to be used if the element title is empty. The title option includes HTML content. HTML code is allowed in the tooltip if the option html is set as true.

<script type="text/javascript">
		delay: { "show": 500, "hide": 100 },
		title:"<strong class='txt-highlight'>Title is from the JavaScript</strong> as given as the Tooltip options.",

The following table shows some more options of the tooltip library function and its default value.

Option Description Default
animation To add fade in / fade out effect to the tooltip popup. true
container To specify the element name within which the tooltip markup should be created dynamically to avoid overflow. false
delay To specify the time in millisecond for the animation effect. 0
html It has boolean value to allow HTML code in the tooltip. true
placement It is to specify the position of the tooltip (top, right, bottom, left) top
template HTML template for the tooltip message. The title text will be included inside the div containing the class name tooltip-inner ‘<div class=”tooltip” role=”tooltip”><div class=”tooltip-arrow”></div><div class=”tooltip-inner”></div></div>’
title It accepts text/HTML to be added in the tooltip popup. If the html is true then the HTML code will be included. Otherwise, the HTML tags are stripped and the text content is included in the tooltip.
trigger event method like hover, focus, and manual that are to be used for triggering the tooltip. It accepts multiple trigger events ‘hover focus’


The following screenshot shows the tooltip popup for the element which has the title attribute. It also shows the tooltip with the text specified in the JavaScript for the element that does not has the title attribute
