Customize the overlay color using the theme's background color

I want to create an overlay on my webpage that covers all the content. However, I'm facing a challenge because my website allows users to customize the theme colors, and the overlay div does not adopt these color changes automatically. To rectify this issue, I have resorted to setting the background-color manually using background-color: rgba( x, y, z, 1.0).

Below is the CSS code I am currently using for the overlay:


.bio-overlay {
    position: fixed; /* Positioned on top of the page content */
    display: block; 
    width: 100%; /* Occupies the entire width of the page */
    height: 100%; /* Occupies the entire height of the page */
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
    z-index: 2048; 
    cursor: pointer; /* Changes cursor to pointer on hover */}

If there is a way to achieve this effect purely with CSS, I would love to know. Otherwise, I am open to implementing a clever JavaScript solution. Thank you!

Answer №1

One approach is to create a class based on the theme structure and use it for the overlay, ensuring that if the theme changes, the overlay color also changes with it.

.backgroundColor {
    background-color: rgba(x, y, z, 1.0);
}

<div class="bio-overlay backgroundColor">
    Content
</div>

Alternatively, if the overlay is nested within the theme, you can target it specifically to assign a background color.

.themeClass .bio-overlay {
    background-color: rgba(x, y, z, 1.0);
}

This method will override the existing .bio-overlay class and inherit the background color from the parent themeClass.

EDIT

In response to your query, you can customize the background color in your stylesheet like this:

.whatevertheme .bio-overlay {
    background-color: _whatever_;
}
.whatevertheme2 .bio-overlay {
    background-color: _whatever2_;
}
....

The location of the style declaration is not significant as long as it is included on the page. However, be aware that this may compromise the separation of themes.
