Customize the colors of the arrows in Bootstrap's carousel

There seems to be a simple solution that I'm missing here. I have images with white backgrounds and I want to customize the arrows on Bootstrap's Carousel to make them more visible. I need help changing the color of the arrows (not the background as I've already tried).

CSS

.carousel-control-prev-icon, .carousel-control-next-icon {
    height: 100px;
    width: 100px;
    outline: black;
    background-color: rgba(0, 0, 0, 0.3);
    background-size: 100%, 100%;
    border-radius: 50%;
    border: 1px solid black;
}

Carousel HTML

<div class = 'col-md-9'>

    <div id="carouselExampleIndicators" class="carousel slide" data-ride="carousel">

        <ol class="carousel-indicators">
            <li data-target="#carouselExampleIndicators" data-slide-to="0" class="active"></li>
            <li data-target="#carouselExampleIndicators" data-slide-to="1"></li>
            <li data-target="#carouselExampleIndicators" data-slide-to="2"></li>
        </ol>

        <div class="carousel-inner" role="listbox">
            <div class="carousel-item active">
                <img class="d-block img-fluid" src="carousel/Bars%20and%20Dots.jpg" alt="First slide" class = 'img-responsive'>
            </div>

            <div class="carousel-item">
                <img class="d-block img-fluid" src="carousel/murial.jpg" alt="Second slide" class = 'img-responsive'>
            </div>

            <div class="carousel-item">
                <img class="d-block img-fluid" src="carousel/Upper%20Partialism%20album%20covers004white.jpg" alt="Third slide" class = 'img-responsive'>
            </div>
        </div>

        <a class="carousel-control-prev" href="#carouselExampleIndicators" role="button" data-slide="prev">
            <span class="carousel-control-prev-icon" aria-hidden="true"></span>
            <span class="sr-only">Previous</span>
        </a>

        <a class="carousel-control-next" href="#carouselExampleIndicators" role="button" data-slide="next">
            <span class="carousel-control-next-icon" aria-hidden="true"></span>
            <span class="sr-only">Next</span>
        </a>

    </div>

Although this post is from some time ago, it was still helpful for me. I have also discovered that in bootstrap v4, you can customize the arrow color by modifying the controls like this:

.carousel-control-prev-icon {
 background-image: url("data:image/svg+xml;charset=utf8,%3Csvg xmlns='http://www.w3.org/2000/svg' fill='%23fff' viewBox='0 0 8 8'%3E%3Cpath d='M5.25 0l-4 4 4 4 1.5-1.5-2.5-2.5 2.5-2.5-1.5-1.5z'/%3E%3C/svg%3E") !important;
}

.carousel-control-next-icon {
  background-image: url("data:image/svg+xml;charset=utf8,%3Csvg xmlns='http://www.w3.org/2000/svg' fill='%23fff' viewBox='0 0 8 8'%3E%3Cpath d='M2.75 0l-1.5 1.5 2.5 2.5-2.5 2.5 1.5 1.5 4-4-4-4z'/%3E%3C/svg%3E") !important;
}

If you change fill='%23fff' to any hexadecimal value that you prefer, you can alter the color. For instance:

fill='%23000' for black, fill='%23ff0000' for red, and so forth. Just note that I have not tested this without using the important declaration.

Answer №2

To change the color to black in Bootstrap 4+, you can simply use the following CSS code:

.carousel-control-next,
.carousel-control-prev /*, .carousel-indicators */ {
    filter: invert(100%);
}

Answer №3

.custom-carousel-control-icons {
  height: 100px;
  width: 100px;
  outline: black;
  background-size: 100%, 100%;
  border-radius: 50%;
  border: 1px solid black;
  background-image: none;
}

.custom-carousel-control-icons .next-icon:after
{
  content: '>';
  font-size: 55px;
  color: red;
}

.custom-carousel-control-icons .prev-icon:after {
  content: '<';
  font-size: 55px;
  color: red;
}

Answer №4

To enhance your design, consider utilizing the following code snippet with fontawesome icons: 

<span><i class="fa fa-angle-left" aria-hidden="true"></i></span>
. By replacing the original code with this new implementation, you can have more flexibility in customizing the appearance using CSS:

<a class="carousel-control-prev" href="#carouselExampleIndicatorsTestim" role="button" data-slide="prev">
    <span><i class="fa fa-angle-left" aria-hidden="true"></i></span>
    <span class="sr-only">Previous</span>
</a>
<a class="carousel-control-next" href="#carouselExampleIndicatorsTestim" role="button" data-slide="next">
    <span><i class="fa fa-angle-right" aria-hidden="true"></i></span>
    <span class="sr-only">Next</span>
</a>

Here is the original code for reference:

<a class="carousel-control-prev" href="#carouselExampleIndicators" role="button" data-slide="prev">
    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
    <span class="sr-only">Previous</span>
</a>

<a class="carousel-control-next" href="#carouselExampleIndicators" role="button" data-slide="next">
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="sr-only">Next</span>
</a>

Answer №6

Bootstrap 4 is currently utilizing a background-image that contains embedded SVG data information specifying the color of the SVG shape. The code looks something like this:

.carousel-control-prev-icon { background-image:url("data:image/svg+xml;charset=utf8,%3Csvg xmlns='http://www.w3.org/2000/svg' fill='%23fff' viewBox='0 0 8 8'%3E%3Cpath d='M5.25 0l-4 4 4 4 1.5-1.5-2.5-2.5 2.5-2.5-1.5-1.5z'/%3E%3C/svg%3E"); }

Take note of the fill='%23fff' part which specifies the color to fill the shape with, in this case #fff (white). To change it to red, simply replace #fff with #f00.

For the next icon, you can also include this adjustment:

.carousel-control-prev-icon {background-image: url("data:image/svg+xml;charset=utf8,%3Csvg xmlns='http://www.w3.org/2000/svg' fill='%23f00' viewBox='0 0 8 8'%3E%3Cpath d='M5.25 0l-4 4 4 4 1.5-1.5-2.5-2.5 2.5-2.5-1.5-1.5z'/%3E%3C/svg%3E"); }

Answer №7

Here is a simple example that has worked well for me:

    .carousel-control-prev,
    .carousel-control-next{
        height: 50px;
        width: 50px;
        outline: $color-white;
        background-size: 100%, 100%;
        border-radius: 50%;
        border: 1px solid $color-white;
        background-color: $color-white;
    }

    .carousel-control-prev-icon { 
        background-image:url("data:image/svg+xml;charset=utf8,%3Csvg xmlns='http://www.w3.org/2000/svg' fill='%23009be1' viewBox='0 0 8 8'%3E%3Cpath d='M5.25 0l-4 4 4 4 1.5-1.5-2.5-2.5 2.5-2.5-1.5-1.5z'/%3E%3C/svg%3E"); 
        width: 30px;
        height: 48px;
    }
    .carousel-control-next-icon { 
        background-image: url("data:image/svg+xml;charset=utf8,%3Csvg xmlns='http://www.w3.org/2000/svg' fill='%23009be1' viewBox='0 0 8 8'%3E%3Cpath d='M2.75 0l-1.5 1.5 2.5 2.5-2.5 2.5 1.5 1.5 4-4-4-4z'/%3E%3C/svg%3E");
        width: 30px;
        height: 48px;
    }

Answer №8

If you want to adjust the color of controls in Bootstrap 4, a simple way is to modify the sass variables directly in your custom.scss file:

$carousel-control-color: #7b277d;

More information on this can be found in a discussion on GitHub at this link

Answer №9

This solution worked perfectly for my project:

.carousel-control-prev-icon {
    background-image: url("data:image/svg+xml,%3csvg xmlns='http://www.w3.org/2000/svg' fill='%23000' width='8' height='8' viewBox='0 0 8 8'%3e%3cpath d='M5.25 0l-4 4 4 4 1.5-1.5L4.25 4l2.5-2.5L5.25 0z'/%3e%3c/svg%3e");
}
      
.carousel-control-next-icon {
    background-image: url("data:image/svg+xml,%3csvg xmlns='http://www.w3.org/2000/svg' fill='%23000' width='8' height='8' viewBox='0 0 8 8'%3e%3cpath d='M2.75 0l-1.5 1.5L3.75 4l-2.5 2.5L2.75 8l4-4-4-4z'/%3e%3c/svg%3e");
}

To customize the appearance, I modified the color in the icon's URL code. By changing this part to black:

"...fill='%23000'..."

Answer №10

If you are working with bootstrap-3, you have the option to use the following code snippet:

.carousel-control span.glyphicon {
    color: red;
}

Answer №11

For those utilizing the bootstrap.min.css file for a carousel:

<a class="left carousel-control" href="#carouselExample" data-slide="prev">
  <span class="glyphicon glyphicon-chevron-left"></span>
  <span class="sr-only">Previous</span>
</a>
<a class="right carousel-control" href="#carouselExample" data-slide="next">
  <span class="glyphicon glyphicon-chevron-right"></span>
  <span class="sr-only">Next</span>
</a>

To customize the carousel controls, locate the "glyphicon-chevron-right" property in the bootstrap.min.css file and include the property "color:red".

Answer №12

I encountered a similar issue where some images appeared too light while others were too dark, making it difficult to see the arrows clearly. To address this problem, I decided to take a more straightforward approach.

Within the modal-body section, I simply removed the following lines:

    <!-- Left and right controls -->
    <a class="carousel-control-prev" href="#id" data-slide="prev">
       <span class="carousel-control-prev-icon"></span>
    </a>
    <a class="carousel-control-next" href="#id" data-slide="next">
      <span class="carousel-control-next-icon"></span>
    </a>

and replaced them with the following in the modal-header section:

    <!-- Left and right controls -->
    <a  href="#gamespandp" data-slide="prev" class="btn btn-outline-secondary btn-sm">&#10094;</a>
    <a  href="#gamespandp"  data-slide="next" class="btn btn-outline-secondary btn-sm">&#10095;</a>

By making this simple change, the indicators are now clearly visible without the need for additional icons or modifications to style sheets. You can still customize the styling according to your preference!

Answer №13

If you want to modify the color, you need to update the style in your CSS file and adjust the fill attribute in the SVG code used as a background-image for the classes .carousel-control-prev-icon and .carousel-control-next-icon

fill='%23fff' simply change fff to the color of your choice, like f00 for red. (You can also use a 6-letter hex code --> %23ff0000)

.carousel-control-pre-icon {background-image: url("data:image/svg+xml,%3csvg xmlns='http://www.w3.org/2000/svg' fill='%23fff' width='8' height='8' viewBox='0 0 8 8'%3e%3cpath d='M5.25 0l-4 4 4 4 1.5-1.5L4.25 4l2.5-2.5L5.25 0z'/%3e%3c/svg%3e");}

for juniors: .carousel-container .carousel .carousel-control-next .carousel-control-next-icon

Answer №14

Incorporating CSS allows for the customization of icon colors through the fill parameter to be applied to control classes and icon classes. Additionally, a hover alpha class can be added to alter background effects:

.carousel-control-prev-icon {background-image: url("data:image/svg+xml,%3csvg xmlns='http://www.w3.org/2000/svg' fill='%23000000' width='8' height='8' viewBox='0 0 8 8'%3e%3cpath d='M5.25 0l-4 4 4 4 1.5-1.5L4.25 4l2.5-2.5L5.25 0z'/%3e%3c/svg%3e");}
.carousel-control-next-icon {background-image: url("data:image/svg+xml,%3csvg xmlns='http://www.w3.org/2000/svg' fill='%23000000' width='8' height='8' viewBox='0 0 8 8'%3e%3cpath d='M2.75 0l-1.5 1.5L3.75 4l-2.5 2.5L2.75 8l4-4-4-4z'/%3e%3c/svg%3e");}
<--! alpha background -->
.carousel-control-next:hover, .carousel-control-prev:hover {
background-color:rgba(0, 0, 0, 0);}

Answer №15

If you want to personalize the color scheme of your carousel controls, captions, and indicators with Sass, simply update these variables:

    $carousel-control-color: 
    $carousel-caption-color: 
    $carousel-indicator-active-bg:

Answer №16

To replace them with Font Awesome using only CSS:

.carousel-control-prev-icon, .carousel-control-next-icon {
  background-image: none;
}

.carousel-control-prev-icon:after, .carousel-control-next-icon:after {     
  content: "\f055";
  font-family: 'Font Awesome 5 Free', sans-serif;
}

.carousel-control-next-icon:after {
  content: "\f056";
}

Answer №17

Using Font Awesome icons:

<!-- Navigation buttons -->
<a class="carousel-control-prev" href="#carousel-example-generic" role="button" data-slide="prev">
  <span class="fa fa-chevron-left fa-lg" style="color:red;"></span>
  <span class="sr-only">Previous</span>
</a>
<a class="carousel-control-next" href="#carousel-example-generic" role="button" data-slide="next">
  <span class="fa fa-chevron-right fa-lg" style="color:red;"></span>
  <span class="sr-only">Next</span>
</a>
