How Can We Make CSS Background Images Accessible to Screen Readers?

Providing Alternative Text for CSS Background Images

While CSS background images can convey valuable information, they typically lack an accessible way for screen readers or users with visual impairments to understand their content. This poses the question: How can we provide alternative text for background images without sacrificing the visual experience?

The answer lies in utilizing the title attribute on the containing element. By assigning a descriptive title to the element that displays the background image, we can convey its purpose and provide screen readers with an accessible alternative.

Example:

HTML:

<div class="hotwire-fitness" title="Fitness Centre"></div>

CSS:

.hotwire-fitness {
    background: url(/prostyle/images/new_amenities.png) -71px 0;
    width: 21px;
    height: 21px;
}

In this example, the div element is assigned the title attribute with the text "Fitness Centre". When a screen reader encounters this element, it will read out the title, providing the user with an understanding of the icon's purpose.
