How to create a tooltip?

I want to make a custom CSS class for tooltip which will wrap a string of length more than 25-30.Usually such a long text doesn't fit into the tootltip text area.

And is there anyway to do this using Tooltip (ui.bootstrap.tooltip) ? Like using custom CSS class to get the desired output.

This is the simple css tooltip - Plunker DEMO

Here is the code Snippet for the same :

.tooltip {
    position: relative;
    display: inline-block;
    border-bottom: 1px dotted black;

.tooltip .tooltiptext {
    visibility: hidden;
    border: 1px solid black;
    color: #000;
    text-align: center;
    border-radius: 6px;
    /* Position the tooltip */
    position: absolute;
    z-index: 1;

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

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

<div class="tooltip">Hover over me 1
  <span class="tooltiptext">Tooltip text</span>
<div class="tooltip">Hover over me 2
  <span class="tooltiptext">Array [1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,,1,11,1,1,1,11,1,,1,1,1,1,1,1,1,1,1,1,1,1,1,1]</span>


The CSS Solution

There is a very simple solution to the problem at hand. What I essentially added is the following CSS code


to the class that surrounds your tooltip text.

What if I am using Angular UI?

For styling a tooltip from angular ui, I added tooltip-class="tooltip" to the tooltip code.

Here is a working demo with angular

This is a modified plunkr obtained from the Angular UI documentation

Here is complete code of custom tooltip in bootstrap

<!DOCTYPE html>
<html lang="en">
  <title>Bootstrap Example</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="">
  <script src=""></script>
  <script src=""></script>

  <style> .tooltip-inner {
  } .tooltip-arrow {
          border-top-color: red;
.tooltip.right .tooltip-inner {
.tooltip.right .tooltip-arrow {
          border-right-color: blue;
.tooltip.bottom .tooltip-inner {
.tooltip.bottom .tooltip-arrow {
          border-bottom-color: green;
.tooltip.left .tooltip-inner {
.tooltip.left .tooltip-arrow {
          border-left-color: yellow;

   <div class="container">
  <div class="row">
    <div class="col-sm-12">
        <h1>Colored Tooltip</h1>
    <div class="col-sm-3">
        <a href="#" data-toggle="tooltip" title="This tooltip is on top!">Hover to see my tooltip</a>
    <div class="col-sm-3">
        <a href="#" data-placement="right" data-toggle="tooltip" title="This tooltip is on the right!">Hover to see my tooltip</a>
    <div class="col-sm-3">
        <a href="#" data-placement="bottom" data-toggle="tooltip" title="This tooltip is on the bottom!">Hover to see my tooltip</a>
    <div class="col-sm-3">
        <a href="#" data-placement="left" data-toggle="tooltip" title="This tooltip is on the left!">Hover to see my tooltip</a>

You can create a use some css tricks which will resize the tooltip according to content.

Here is some example with assumptions of width and height.

    background:#000;/*change accordingly*/

Above css will create a div with fix maximum width and resizeable height which will fit you content.
