如何自定义Bootstrap轮播控件

Question

Can you please let me know how I can customize the Bootstrap Carousel Controls for example I would like to change the size of the controls, or bg colors and How I can add background image to the controls? I tried to replace the ‹ with bootstrap Icons but they positioned at the top of control and didn't work properly

<a class="carousel-control left" href="#this-carousel-id" data-slide="prev"><i class=" icon-arrow-right icon-white"></i></a>
<a class="carousel-control right" href="#this-carousel-id" data-slide="next">&rsaquo;</a>

the output looks like:

Answer 1

How familiar are you with CSS?

What I see in your screenshot could be adjusted via font-size and line-height properties

Bootstrap is a CSS framework so customization is just a matter of overriding defaults, often using an id tag or something similar

Answer 2

This worked for me for the size and color:

.carousel-control .icon-prev, .carousel-control .icon-next {
    font-size: 100px; 
    margin-top: -50px;
    color: #fff;
}

Answer 3

one quick way to change the colour is to override the inline svg background:

.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");
}

look for the fill='%23fff' part and change the colour, from white to something else: fill='%23444' or fill='RoyalBlue'
