Is there a way to adjust the transparency of an image without affecting any overlaid text while using Bootstrap's carousel feature?

I am currently working with Bootstrap v4 to build a carousel featuring an image with caption text. My goal is to have the image faded while leaving the text unaffected. Despite trying several non-Bootstrap solutions, I have been unsuccessful in achieving the desired effect. Any assistance would be greatly appreciated :(

Here is the link to the development site:

Below is the code snippet:

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

  <!-- Indicators -->
  <ol class="carousel-indicators">
    <li data-target="#home-page-carousel" data-slide-to="0" class="active"></li>
    <li data-target="#home-page-carousel" data-slide-to="1"></li>
  </ol>

  <!-- Content -->
  <div class="carousel-inner" role="listbox"> 

    <!-- Slide 1 -->
    <div class="carousel-item active"> <img src="<?php echo SITE_IMG . 'L1.jpg'; ?>" alt="Liverpool City Centre">
      <div class="carousel-caption">
        <h3>This is a title</h3>
        <p>This is some text that is relevant to the title above</p>
      </div>
    </div>

    <!-- Slide 2 -->

    <div class="carousel-item"> <img src="<?php echo SITE_IMG . 'L1.jpg'; ?>" alt="Liverpool City Centre">
      <div class="carousel-caption">
        <h3>This is a title</h3>
        <p>This is some text that is relevant to the title above</p>
      </div>
    </div>
  </div>

  <!-- Previous/Next controls --> 
  <a class="left carousel-control" href="#home-page-carousel" role="button" data-slide="prev"> <span class="icon-prev" aria-hidden="true"></span> <span class="sr-only">Previous</span> </a> <a class="right carousel-control" href="#home-page-carousel" role="button" data-slide="next"> <span class="icon-next" aria-hidden="true"></span> <span class="sr-only">Next</span> </a> </div>

<!-- Center the image -->
<style scoped>
.carousel-item img{
    margin: 0 auto;
}
</style>

Answer №1

After reviewing the provided HTML code

<div class="carousel-item"> <img src="<?php echo SITE_IMG . 'L1.jpg'; ?>" alt="Liverpool City Centre">
      <div class="carousel-caption">
        <h3>This is a title</h3>
        <p>This is some text that is relevant to the title above</p>
      </div>
    </div>
  </div>

Your request is for:

.carousel-item img {
     opacity: /* whatever */
   }

Answer №2

To achieve the desired effect, one simple solution is to adjust the opacity of the image in question:

.carousel-item img {
  -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=50)"; /* Support for IE 8 */
  filter: alpha(opacity=50);                                         /* For IE 5-7 */
  -moz-opacity: 0.5;                                                 /* Compatible with Netscape/Firefox */
  -khtml-opacity: 0.5;                                               /* Works with Safari 1.x */
  opacity: 0.5;                                                      /* Modern browsers support this property */
}
