Creating opaque elements within a see-through container

I'm working with a bootstrap carousel and I want to set the background image of each carousel-item to be .4 opacity, while keeping the caption at full 1 opacity. Is there a way to achieve this?

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

            <!-- Slide One - Set the background image for this slide in the line below -->
            <div class="carousel-item active" style="background-image: url('img/banner.jpg')">
                <div class="carousel-caption d-none d-md-block">
                    <h2 class="display-4">First Slide</h2>
                    <p class="lead">This is a description for the first slide.</p>
                </div>
            </div>

        </div>
    </div>

Answer №1

When it comes to opacity, the default initial value is 1. It's important to note that opacity is not inherited; however, the parent's opacity affects everything within it. If you want a child element to be less transparent than its parent, some tricks may be necessary.

To achieve this, you can change the position of the child element in your HTML code and then apply the following CSS properties:

.child {
    position: relative;
    top: 5rem;
}
.parent {
    opacity: 0;
}

I hope you find this information helpful!
