[html] Change Bootstrap tooltip color

What I'm trying to do is change the tooltip color to red. However, I also want to have multiple other colors so I don't simply want to replace the original tooltip's color.

How would I go about doing this?

$(document).ready(function(){_x000D_
  $('.tooltips-elements')_x000D_
    .tooltip()_x000D_
    .each(function() {_x000D_
        var color = $(this).data('color');_x000D_
        $(this).hover(function(){_x000D_
         var aria = $(this).attr('aria-describedby');_x000D_
         $('#' + aria).find('.tooltip-inner').css({_x000D_
          "background": color,_x000D_
          "color" : "#333",_x000D_
          "margin-left" : "10px",_x000D_
          "font-weight" : "700",_x000D_
          "font-family" : "Open Sans",_x000D_
          "font-size" : "13px",_x000D_
         });_x000D_
         $('#' + aria).find('.tooltip-arrow').css({_x000D_
          "border-bottom-color" : color,_x000D_
         });_x000D_
        });_x000D_
    });_x000D_
});

Check this maybe it can help you. You can have multiple tooltips color.

We are using bootstrap 3.0 on our website, but none of the above steps worked in updating the styling of the tooltip. But I did find a solution using jQueryUI styling instead

https://jqueryui.com/tooltip/#custom-style

CSS

  .ui-tooltip, .arrow:after {
    background: black;
    border: 2px solid white;
  }
  .ui-tooltip {
    padding: 10px 20px;
    color: white;
    border-radius: 20px;
    font: bold 14px "Helvetica Neue", Sans-Serif;
    text-transform: uppercase;
    box-shadow: 0 0 7px black;
  }

HTML

<div class="qu_help" data-toggle="tooltip" title="Some Random Title"> 
   <span class="glyphicon glyphicon-question-sign" aria-hidden="true"></span>
</div>

I'm adding this answer in case someone else is in a similar situation as I was.

For Bootstrap 4 with dependency on tether.js the .tooltip-arrow classes have been replaced with .tooltip.bs-tether-element-attached-[position]{...}

Here is how I changed color and thickened bottom arrow. For every pixel added to border-width, I had to subtract a pixel from "bottom" position.

.tooltip.bs-tether-element-attached-bottom .tooltip-inner::before, .tooltip.tooltip-bottom .tooltip-inner::before {

    border-top-color: #d19b3d !important;
    border-width: 10px 10px 0;
    bottom: -5px;
}

You'll have to adjust for other positions, i.e. for .tooltip.bs-tether-element-attached-left you would adjust border-right, and reposition if raising border-width by subtracting pixels from "left", etc.

The only way working for me:

.tooltip.bottom .tooltip-arrow{
    border-bottom-color:#F00;
}

Oleg's answer https://stackoverflow.com/a/42994192/9921853 is the best there. It allows to apply the tooltip styles to the dynamically created elements. However it doesn't work for Bootstrap 4. It should be slightly modified:

Bootstrap 3:

$(document).on('inserted.bs.tooltip', function(e) {
    var tooltip = $(e.target).data('bs.tooltip');
    tooltip.$tip.addClass($(e.target).data('tooltip-custom-class'));
});

Example: https://www.bootply.com/UORR04ncTP

Bootstrap 4:

$(document).on('inserted.bs.tooltip', function(e) {
    var tooltip = $(e.target).data('bs.tooltip');
    $(tooltip.tip).addClass($(e.target).data('tooltip-custom-class'));
});

Example: https://jsfiddle.net/nsmcan/naq530hx

Full Solution (Bootstrap 3)

JS

$(document).on('inserted.bs.tooltip', function(e) {
    var tooltip = $(e.target).data('bs.tooltip');
    tooltip.$tip.addClass($(e.target).data('tooltip-custom-classes'));
});

$('body').tooltip({ 
    selector: "[title]", 
    html: true
});

HTML

<h1>Test tooltip styling</h1>
<div><span title="Long-long-long tooltip doesn't fit the single line">Hover over me 1</span></div>
<div><span data-tooltip-custom-classes="tooltip-left" data-container="body" title="Example (left aligned):<br>Tooltip doesn't fit the single line, and is not a sibling">Hover over me 2</span></div>
<div><span class="text-danger" data-tooltip-custom-classes="tooltip-large tooltip-left tooltip-danger" title="Example (left aligned):<br>This long text we want to have in the single line">Hover over me 3</span></div>

CSS

.tooltip.tooltip-large > .tooltip-inner {
    max-width: 300px;
}
.tooltip.tooltip-left > .tooltip-inner {
    text-align: left;
}

.tooltip.top.tooltip-danger > .tooltip-arrow {
    border-top-color: #d9534f;
}
.tooltip.top-left.tooltip-danger > .tooltip-arrow {
    border-top-color: #d9534f;
}
.tooltip.top-right.tooltip-danger > .tooltip-arrow {
    border-top-color:#d9534f;
}
.tooltip.right.tooltip-danger > .tooltip-arrow {
    border-right-color: #d9534f;
}
.tooltip.left.tooltip-danger > .tooltip-arrow {
    border-left-color: #d9534f;
}
.tooltip.bottom.tooltip-danger > .tooltip-arrow {
    border-bottom-color: #d9534f;
}
.tooltip.bottom-left.tooltip-danger > .tooltip-arrow {
    border-bottom-color: #d9534f;
}
.tooltip.bottom-right.tooltip-danger > .tooltip-arrow {
    border-bottom-color: #d9534f;
}
.tooltip.tooltip-danger > .tooltip-inner {
    background-color: #d9534f;
}

You can use this way:

And in the CSS:

.tooltip-arrow,
.red-tooltip + .tooltip > .tooltip-inner {background-color: #000;}

Non of above answers works fine in case of container: 'body', and the following solution does:

// Assign custom CSS class after the tooltip template has been added to the DOM
$(document).on('inserted.bs.tooltip', function(e) {
    var tooltip = $(e.target).data('bs.tooltip');
    tooltip.$tip.addClass($(e.target).data('tooltip-custom-class'));
});

And a simple CSS snippet:

.tooltip.tooltip-danger > .tooltip-inner {
    background-color: #d9534f;
}

.tooltip.tooltip-danger.left > .tooltip-arrow {
    border-left-color: #d9534f;
}

Now you can init your tooltip as a usual, passing custom CSS class via data-tooltip-custom-class attribute:

<span class="js-tooltip">Hover me totally</span>

<script>
$('.js-tooltip')
    .data('tooltip-custom-class', 'tooltip-danger')
    .tooltip(/*your options*/)
;
</script>

You can use the quickapproach mentioned in other answers if you just want to change color. However if you are using Bootstrap than you should use themes so that look and feel is consistent. Unfortunately there is no built-in support for themes for Bootstrap so I wrote little piece of CSS that does this. You basically get tooltip-info, tooltip-warning etc classes that you can add to the element to apply theme.

You can find this code along with fiddle, examples and more explanation in this answer: https://stackoverflow.com/a/20880312/207661

my jQuery fix:

HTML:

   <a href="#" data-toggle="tooltip" data-placement="right" data-original-title="some text">
       <span class="glyphicon glyphicon-question-sign"></span>
   </a>

jQuery:

$('[data-toggle="tooltip"]').hover(function(){
    $('.tooltip-inner').css('min-width', '400px');
    $('.tooltip-inner').css('color', 'red');
});

Important to note, as of Bootstrap 4 you can customize these styles directly in your Bootstrap Sass variables file, so in _variables.scss you have these options:

//== Tooltips
//
//##

// ** Tooltip max width
$tooltip-max-width:           200px !default;
// ** Tooltip text color
$tooltip-color:               #fff !default;
// ** Tooltip background color
$tooltip-bg:                  #000 !default;
$tooltip-opacity:             .9 !default;

// ** Tooltip arrow width
$tooltip-arrow-width:         5px !default;
// ** Tooltip arrow color
$tooltip-arrow-color:         $tooltip-bg !default;

See here: http://v4-alpha.getbootstrap.com/getting-started/options/

Best to work in Sass and compile as you go with Grunt or Gulp build tools.

It will change the color of the tooltip in bootstrap4 you can use bottom, left, right to add CSS for respective in place of top in .bs-tooltip-top

.tooltip-inner {
background-color: #00acd6 !important;
color: #fff;
}
.bs-tooltip-top .arrow::before, .bs-tooltip-auto[x-placement^="top"] 
.arrow::before {
border-top-color: #00acd6;
}

The only way working for me:

$(document).ready(function() {_x000D_
  //initializing tooltip_x000D_
  $('[data-toggle="tooltip"]').tooltip();_x000D_
});

.tooltip-inner {_x000D_
  background-color: #00acd6 !important;_x000D_
  /*!important is not necessary if you place custom.css at the end of your css calls. For the purpose of this demo, it seems to be required in SO snippet*/_x000D_
  color: #fff;_x000D_
}_x000D_
_x000D_
.tooltip.top .tooltip-arrow {_x000D_
  border-top-color: #00acd6;_x000D_
}_x000D_
_x000D_
.tooltip.right .tooltip-arrow {_x000D_
  border-right-color: #00acd6;_x000D_
}_x000D_
_x000D_
.tooltip.bottom .tooltip-arrow {_x000D_
  border-bottom-color: #00acd6;_x000D_
}_x000D_
_x000D_
.tooltip.left .tooltip-arrow {_x000D_
  border-left-color: #00acd6;_x000D_
}

Within your BS4 project, if you are able to compile SASS code, you can take advantage of creating a mixin to manage the color scheme of tooltips from any direction.

Benefits of this approach:

• You don't have to add on additional javaScript/jQuery for something that involves styling.
• You leverage SASS to dynamically handle the branding for you.
• You can easily control which tooltips have what color(s) and direction(s).

Here's one of many ways in which you can implement this:

Create your original mixin:

• Provide a variable for a color
• Set 2 parameters (one for the custom class name of your tooltip, and the other for the color). I also add default values for these parameters (optional).

• Create a list and loop over it to cover all 4 possible directions

  //define a color
  $m-color-blue: #004c97;
  
  //create a mixin with parameters and default value
  @mixin m-tooltip-color-direction($name:'.mtootltip', $color:$m-color-blue) {
  
  //reference your custom class name
  #{$name} {
      .tooltip-inner {
          background-color: $color;
      }
  
      //create a list of possible directions
      $directions: top bottom left right;
  
      //loop through the list
      @each $direction in $directions {
          &.bs-tooltip-#{$direction} .arrow:before,
           .bs-tooltip-auto[x-placement^="$direction"] .arrow:before {
              border-#{$direction}-color: $color !important;
          }
       }
    }
  }
  

  
  

Call your mixin (adjust class name and color)

• Within your main .scss file call your mixin like so:

  @include m-tooltip-color-direction('.mtooltip', $m-color-blue);
  

Set your BS4 Tooltip in your layout (adjust direction)

• Finally, add a BS4 tooltip to your layout, and give it a custom class for flexibility. This BS4 resource talks about using template as an option. We'll be using that to add our custom class.

• The following example adds a tooltip on an info icon badge:

   <span class="badge badge-pill badge-primary" data-toggle="tooltip" data-placement="right" data-html="true" data-template="<div class='tooltip mtooltip' role='tooltip'><div class='arrow'></div><div class='tooltip-inner'></div></div>" title="<h1 class='text-white'>Tooltip</h1> on bottom">i</span>
  

With this setup you can adjust the class name, color and direction of your tooltip without touching your original mixin. How cool is that :)

Hope this helps!

For the arrow color, you can use this:

.tooltip .tooltip-arrow {border-top: 5px solid red !important;}

In Bootstrap 3 (not tested in 4) you can override default colors with using a template when creating the tooltip. With this method you can specify tooltip colors runtime:

var bgColor = '#dd0000'; //red
var textColor = '#ffffff'; //white

$('#yourControlId').tooltip({
    placement: "top",
    template: '<div class="tooltip" role="tooltip"><div class="tooltip-arrow" style="border-top-color:' + bgColor + ';"></div><div class="tooltip-inner" style="background-color:' + bgColor + ';color:' + textColor + ';"></div></div>'
});

The template is based on original tooltip template. I only added the color styles. The placement must be top, because of arrow styling. (I haven't tried other placement types)

This is already been answered right but i think i should give my opinion too. Like cozen says this is a border, and for it to work you must specify the classes to format this in the same way that bootstrap specifies it. So, you can do this

.tooltip .tooltip-inner {background-color: #00a8c4; color: black;} 
.tooltip.top .tooltip-arrow {border-top-color: #00a8c4;}

or you can do the next one, just for the tooltip-arrow but you must add the !important, so that it overwrites the bootstrap css

.tooltip-arrow {border-top-color: #00a8c4!important;}

The arrow is a border.
You need to change for each arrow the color corresponding.

.tooltip.top .tooltip-arrow {
  border-top-color: @color;
}
.tooltip.top-left .tooltip-arrow {
  border-top-color: @color;
}
.tooltip.top-right .tooltip-arrow {
  border-top-color:@color;
}
.tooltip.right .tooltip-arrow {
  border-right-color: @color;
}
.tooltip.left .tooltip-arrow {
  border-left-color: @color;
}
.tooltip.bottom .tooltip-arrow {
  border-bottom-color: @color;
}
.tooltip.bottom-left .tooltip-arrow {
  border-bottom-color: @color;
}
.tooltip.bottom-right .tooltip-arrow {
  border-bottom-color: @color;
}
.tooltip > .tooltip-inner {
  background-color: @color;
  font-size: @font-size-small;
}

However If i want to add a class to change the color (like in the fiddle with '.class + .tooltip...' it doesn't work (bootstrap 3).
If someone know how to handle that ?!?

This is true solution

^_^

.tooltip { 
    font-family: inherit; 
} 
.tooltip-inner { 
    background-color: #5264e9; 
}
.bs-tooltip-auto[x-placement^=bottom] .arrow::before,
.bs-tooltip-bottom .arrow::before { 
    border-bottom-color: #5264e9;
}

This worked for me .

.tooltip .arrow:before {
    border-top-color: #008ec3 !important;
}

.tooltip .tooltip-inner {
    background-color: #008ec3;
}

This easy method works for me when i want to change the background color of the bootstrap tooltips:

$(function(){
    //$('.tooltips.red-tooltip').tooltip().data('bs.tooltip').tip().addClass('red-tooltip');
    $('.tooltips.red-tooltip').tooltip().data('tooltip').tip().addClass('red-tooltip');
});

.red-tooltip.tooltip.tooltip.bottom .tooltip-arrow, 
.red-tooltip.tooltip.tooltip.bottom-left .tooltip-arrow,
.red-tooltip.tooltip.tooltip.bottom-right .tooltip-arrow{border-bottom-color: red;}
.red-tooltip.tooltip.top .tooltip-arrow {border-top-color: red;}
.red-tooltip.tooltip.left .tooltip-arrow {border-left-color: red;}
.red-tooltip.tooltip.right .tooltip-arrow {border-right-color: red;}
.red-tooltip.tooltip > .tooltip-inner{background-color:red;}

• jsfiddle Live Demo

Note A:

If js code include .data('tooltip') not working for you then please comment its line and uncomment js code include .data('bs-tooltip').

Note B:

If your bootstrap tooltip function add a tooltip to the end of body (not right after the element), my solution works well yet but some other answers in this pages did not works like @Praveen Kumar and @technoTarek in this scenario.

Note C:

This codes support tooltip arrow color in all placements of the tooltip (top,bottom,left,right).

Bootstrap 2

If you want to change the caret/arrow as well, do the following:

.red-tooltip + .tooltip > .tooltip-inner {background-color: #f00;}
.red-tooltip + .tooltip > .tooltip-arrow {border-bottom-color: #f00;}

or

.red-tooltip + .tooltip > .tooltip-inner, .red-tooltip + .tooltip > .tooltip-arrow {background-color: #f00;}

jsFiddle: http://jsfiddle.net/technotarek/2htZe/

UPDATE: Bootstrap 3

You have to be specific for the direction of the tooltip in Bootstrap 3. For example:

.tooltip.top .tooltip-inner {
    background-color:red;
}
.tooltip.top .tooltip-arrow {
      border-top-color: red;
}

jsFiddle for all tooltip directions using Bootstrap 3: http://jsfiddle.net/technotarek/L2rLE/

If you want to customize the tooltip as white background with black text, We can go through this. Here we are using tooltip with anchor tag

<div id='container-light' class='tooltip-light'>
<a href="#" data-container='#container-light' data-toggle="tooltip" title="Tooltip text">Hover
    over me</a>

Seems to have changed in Bootstrap 4

If you want to change color of a bottom placed tooltip in red, just add this to your CSS :

.tooltip-inner {
    background-color: #f00;
}

.bs-tooltip-bottom .arrow::before {
    border-bottom-color: #f00;
}

Here is tooltip code in boostrap...

}

BootStrap 4

When using BootStrap 4 the tooltip is appended to the bottom of the body tag. If your tooltip is a child of another tag there is no way to target the tooltip using css. The only way I've found that works is using the inserted.bs.tooltip event and adding a class to the inner div and the arrow. Then you can target the class in css.

// initialize tooltips_x000D_
$('[data-toggle="tooltip"]').tooltip(); _x000D_
_x000D_
// Add the classes to the toolip when it is created_x000D_
$('[data-toggle="tooltip"]').on('inserted.bs.tooltip',function () {_x000D_
    var thisClass = $(this).attr("class");_x000D_
    $('.tooltip-inner').addClass(thisClass);_x000D_
    $('.arrow').addClass(thisClass + "-arrow");_x000D_
});

/* style the tooltip box and arrow based on your class*/_x000D_
.bs-tooltip-left .redTip {_x000D_
    background-color: red !important_x000D_
}_x000D_
.bs-tooltip-left .redTip-arrow::before {_x000D_
    border-left-color: red !important_x000D_
}

<p>Show a red tooltip <a href="#" class="redTip" data-toggle="tooltip" data-placement="left" title="You Did It!">Hover over me</a></p>

Here's a SCSS code (compiled css below) that will help you to easily control the tooltip colors, including the arrow (border and background for the arrow as well):

Note: you might need to add "important" in some places in order for the CSS rules to take effect. Note #2: the style here only works for TOP and BOTTOM tooltip layouts. Feel free to add some more styling (&.bs-tooltip-left, &.bs-tooltip-right, etc)

SCSS:

$tt-text-color: lime;
$tt-border-color: lime;
$tt-bg-color: black;
$arrow-border-color: lime;
$arrow-bg-color: black;

.tooltip {
  .tooltip-inner {
    background: $tt-bg-color;
    color: $tt-text-color;
    border: 2px solid $tt-border-color;
  }
  .arrow {
    width: 11px;
    height: 11px;
    border: 2px solid $arrow-border-color;
    bottom: 1px;
    &:before {
      width: 11px;
      height: 11px;
      background: $arrow-bg-color;
      border: 0;
    }
  }
  &.bs-tooltip-top {
    .arrow {
      transform: rotate(-135deg);
    }
  }
  &.bs-tooltip-bottom {
    .arrow {
      transform: rotate(135deg);
      top: 2px;
    }
  }
}

CSS:

.tooltip .tooltip-inner {
  background: black;
  color: lime;
  border: 2px solid lime;
}
.tooltip .arrow {
  width: 11px;
  height: 11px;
  border: 2px solid lime;
  bottom: 1px;
}
.tooltip .arrow:before {
  width: 11px;
  height: 11px;
  background: black;
  border: 0;
}
.tooltip.bs-tooltip-top .arrow {
  transform: rotate(-135deg);
}
.tooltip.bs-tooltip-bottom .arrow {
  transform: rotate(135deg);
  top: 2px;
}

Live Example:

jQuery(document).ready(function(){_x000D_
 $('a').tooltip();_x000D_
});

.tooltip .tooltip-inner {_x000D_
  background: black;_x000D_
  color: lime;_x000D_
  border: 2px solid lime;_x000D_

You can use this to solve your problem. I checked it in my project and it works fine.

<a class="btn btn-sm btn-success media-tooltip" href="#" data-toggle="tooltip" data-placement="bottom" title="Download Now">Download Now</a>
    .media-tooltip + .tooltip .tooltip-inner {
        font-size: 14px; 
        font-weight: 700;
        color: rgb( 37, 207, 187 ); 
        border-width: 1px;
        border-color: rgb( 37, 207, 187 );
        border-style: solid;
        background-color: rgb( 219, 242, 239 );
        padding: 10px;
        border-radius: 0;
    } 
    .media-tooltip + .tooltip > .tooltip-arrow{display: none;}
    .media-tooltip + .tooltip .tooltip-inner:after, .media-tooltip + .tooltip .tooltip-inner:before {
         bottom: 89%;
         left: 50%;
         border: solid transparent;
         content: " ";
         height: 0;
         width: 0;
         position: absolute;
         pointer-events: none;
    }

    .media-tooltip + .tooltip .tooltip-inner:after {
        border-color: rgba(219, 242, 239, 0);
        border-bottom-color: #dbf2ef;
        border-width: 10px;
        margin-left: -10px;
    }
    .media-tooltip + .tooltip .tooltip-inner:before {
        border-color: rgba(37, 207, 187, 0);
        border-bottom-color: #25cfbb;
        border-width: 11px;
        margin-left: -11px;
    }

for Bootstrap 4 version via CSS:

if you want to change the background color of balloon:

/* change style balloon */
.tooltip-inner {
    background-color: green !important;
    color: #fff;
}

if you want to change the arrow when appear in bottom position:

/* change style arrow */
.bs-tooltip-auto[x-placement^=bottom] .arrow::before, .bs-tooltip-bottom .arrow::before {
    border-bottom-color: #f00;
}

Hope help you

For bootstrap4 I used code:

$('[data-toggle="tooltip"]').tooltip();

.tooltip-inner {
  background-color: #f00 !important;
  color: #f00 ;
}
.bs-tooltip-top .arrow::before, .bs-tooltip-auto[x-placement^="top"] .arrow::before {
  border-top-color: #f00 !important;
}

.bs-tooltip-right .arrow::before, .bs-tooltip-auto[x-placement^="right"] .arrow::before {
  border-right-color: #f00 !important;
}


.bs-tooltip-bottom .arrow::before, .bs-tooltip-auto[x-placement^="bottom"] .arrow::before {
  border-bottom-color: #f00 !important;
}


.bs-tooltip-left .arrow::before, .bs-tooltip-auto[x-placement^="left"] .arrow::before {
  border-left-color: #f00 !important;
}

<a title="This is an example" data-toggle="tooltip">Hover me</a>

Bootstrap 3 + SASS for bottom tooltip :

.red-tooltip {
    & + .tooltip.bottom {
          .tooltip-inner{background-color:$red;}
          .tooltip-arrow {border-bottom-color: $red;}
    }
}

For the arrow, first confirm that which direction you are using. For example, i am using left direction, then it should be

.tooltip .tooltip-inner {
    background-color:#2fa5fb;
}
.tooltip.left > .tooltip-arrow {
   border-left-color: #2fa5fb;
}

If you want to use jQuery you can try this:

$('[data-toggle="tooltip"]').on('shown.bs.tooltip', function(){
    $('.tooltip.bottom .tooltip-arrow').css('border-bottom-color', 'red');
    $('.tooltip-inner').css('background-color', 'red');
});
