In today’s mobile-first world, user experience is crucial, especially when dealing with modals. Regular Bootstrap modals can create additional scrolling issues, particularly on mobile devices. The Bootstrap Mobile FullScreen Modal offers a simple, CSS-only solution to this problem, providing a more native experience similar to ZURB Foundation modals.

What is a FullScreen Modal?

A FullScreen Modal expands to take up the entire screen on mobile devices. This eliminates unnecessary vertical scrolling, allowing users to access content quickly and efficiently. You can see the difference in the user experience between a regular modal and a full-screen modal:

• Regular Bootstrap 4 Modal on Phone
• Fullscreen Bootstrap 4 Modal on Phone

How to Use the FullScreen Modal

Implementing the FullScreen Modal is simple and can be done through either GitHub or npm with the package name bootstrap4-fs-modal. Below are the steps to get you started:

Step 1: Include the CSS

First, include the CSS file from the dist folder in your HTML:

<link href="dist/css/bootstrap-fs-modal.min.css" rel="stylesheet">

Step 2: Adding Styles to Modals

You have two approaches to activate the full-screen styles:

• Add the class modal-fullscreen directly to the modals you want to apply
• Add the class bootstrap-fs-modal to the container element which will style all modals inside

Step 3: Adjust the Modal Footer

If your modal has large text buttons, consider using a fixed bottom modal footer by applying the modal-fullscreen-bottom-footer class to the modal or its container.

Example Implementation

Here’s an example of how to implement the modal in your HTML:

<div class="modal fade modal-fullscreen">
    ...
</div>

<div class="bootstrap-fs-modal">
    <div class="modal fade">
        ...
    </div>
</div>

Button Customization

The plugin modifies the modal footer by placing it at the top and ensuring uniform size and alignment for icons from libraries such as Font Awesome and Google Material. Here’s an example of how the buttons can be structured:

<div class="modal-footer">
    <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button> 
    <button type="button" id="btnTestRefreshSmall" class="btn btn-default">
       <span class="d-none d-md-inline">Reload</span>
       <span class="d-md-none">Reload</span>
    </button>
    <button type="button" class="btn btn-default">
       <span class="d-none d-md-inline">Reload</span>
       <i class="d-md-none fa fa-refresh fa-fw"></i>
    </button>
    <button type="button" class="btn btn-default">
       <span class="d-none d-md-inline">Details</span>
       <i class="d-md-none material-icons">info</i>
    </button>
</div>

Troubleshooting

If you encounter issues while implementing the FullScreen Modal, consider the following troubleshooting tips:

• Make sure the CSS file path is correct and properly linked.
• Check for any conflicting CSS rules that might interfere with the modal styling.
• Ensure you are using the correct classes as specified in this guide.
• If buttons do not appear or behave as expected, verify that you haven’t hidden them via the data-dismiss attribute.
