Bootstrap Mobile FullScreen Modal

A simple way to improve UX of Bootstrap 3 modals on mobile phones.

Note: Bootstrap 4 version of this plugin is available here - https://github.com/keaukraine/bootstrap4-fs-modal

Regular Bootstrap 3 modals (with a lot of content) on mobile devices can cause additional scrolling to get to the bottom buttons of modal.

Fullscreen modal provides more native user experience on mobile phones, here is side-by-side comparison of regular and fullscreen modals:

Fullscreen modal does not affect modals in large viewports, and applies these styles only on mobile devices.

How to Use

You can obtain plugin either from GitHub or from npm, package name is bootstrap-fs-modal.

First, include CSS and JS from dist folder:

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

Then, you have to add CSS class modal-fullscreen to modals which you want to work full-screen.

Plugin can create either text or icon buttons. For buttons to appear as icons, you will need to make a little modification of HTML. Plugin processes all buttons in footer except the ones with data-dismiss="modal" attribute (close button, which will be always added automatically), and adds them either as text or as icon button. Icon for button can be either Glyphicon of Font Awesome icon and is set by data-glyphicon or data-faicon attribute. If one of these attributes is set, it will add button with provided icon. If icon attribute is not set or empty, it will create text button instead. Plugin will try to apply short text by looking for short button text in data-mobile-text attribute and falling back to button text if attribute is not set.

Example:

<div class="modal fade modal-fullscreen" id="modal" tabindex="-1" role="dialog" aria-labelledby="modalLabel">
...
<div class="modal-footer">
  <button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button> <!-- will be skipped -->
  <button type="button" class="btn btn-default" data-glyphicon="glyphicon-refresh">Reload Data</button> <!-- Glyphicon button -->
  <button type="button" id="btnTestSettingsFAButtons" class="btn btn-default" data-faicon="fa-cog">Settings</button> <!-- Font Awesome icon button -->
  <button type="button" id="btnTestRefreshTextButtons" class="btn btn-default" data-mobile-text="Reload">Reload Data</button> <!-- text button with short text -->
  <button type="button" id="btnTestSaveTextButtons" class="btn btn-default btn-primary">Save</button> <!-- text button with default text -->
</div>

That's all you need. JS automatically tracks show.bs.modal events and duplicates all buttons to modal header, wiring click events to original buttons.
