Adjust the opacity of a div's background without impacting the children elements

I am currently working on a dynamic content display in my HTML page using some knockout code. The setup looks like this:

<section id="picturesSection" class="background-image" data-bind="foreach: { data: people, as: 'person'}">
    <div class="cardPositioning panel panel-primary">
        <div class="panel-heading">
            <h3 class="panel-title" data-bind="text: person.Name"></h3>
        </div>
        <header>
            <img width="256" height="256" data-bind="attr:{src: 'app/' + person.srcImage}">
        </header>
        <footer>
            <p class="nameEmployeePos" data-bind="text: person.DateOfBirth"></p>
            <p class="nameEmployeePos" data-bind="text: person.Role"></p>
            <p class="nameEmployeePos" data-bind="text: person.Email"></p>
        </footer>
    </div>
</section>

In the CSS file, I have defined the following for the background image:

.background-image {
    background-image: url("../Images/blocks.png");
    width: 100%;
    z-index: 10;
    background-position-x: 1400px;
    background-position-y: 400px;
    background-repeat: no-repeat;
}

Now, I want to adjust the opacity of the image without affecting the entire div. How can I achieve this?

Answer №1

My personal approach to achieving this on my website involved creating a separate div and nesting the original div within it. I then proceeded to modify the background-color using background-color:rgba

This method worked for me, but there is no guarantee that it will work for everyone.

Answer №2

To create a transparent effect, simply include the following CSS code:

.transparent-background {
    opacity: 0.7;
    filter: alpha(opacity=70); /* For compatibility with IE8 and below */
}

Now you can easily apply this class to any element with a background image.
