The importance of CSS z-index in optimizing for mobile responsiveness

In my jquery modal dialog box, I wanted to create a shadow effect only between the dialog box and the screen. To achieve this, I added an overlay using a <div>:

<div id="overlay" class="overlay btn-hidden"></div>
<div id="myDialogBox" name="myDialogBox" class="myDialogBox"></div>

I then styled it in CSS like so:

.myDialogBox {
    z-index: 999 !important;
}

.overlay {
    z-index: 800 !important;
    position: fixed !important;
}

Everything seemed to work fine on desktop, with the overlay positioned right behind the dialog box. However, when testing on Chrome by switching from desktop to mobile view, I noticed that the overlay was appearing on top of the dialog box, making it difficult to interact with. I attempted setting position: relative for the overlay within a 

@media screen and (max-width: 769px)
query for mobile screens, but the overlay didn't even show up. Is there a solution to ensure the overlay stays behind the modal dialog box on both desktop and mobile screens?

Answer №1

After careful consideration, I ultimately chose to retain the 

@media screen and (min-width: 769px)
rule to trigger the overlay exclusively on desktop screens. This decision was made due to the fact that on mobile devices, the dialog window already covers a significant portion of the screen, making the overlay unnecessary. Nonetheless, I appreciate all the input received! Cheers! :-)
