Admin CSS Styles

All Bootstrap 4 CSS styles and classes are accessible within the LUYA admin interface. In addition to these, LUYA offers generic CSS classes for buttons, complete with predefined icons and colors.


The btn class from Bootstrap 4 is enhanced with predefined colors corresponding to specific functions, such as save, delete, and cancel. These classes are accessible throughout the admin interface:

<button type="button" class="btn btn-save">Save</button>
<button type="button" class="btn btn-delete">Delete</button>
<button type="button" class="btn btn-cancel">Cancel</button>
<button type="button" class="btn btn-edit">Edit</button>
<button type="button" class="btn btn-add">Add</button>
<button type="button" class="btn btn-help">Help</button>
<button type="button" class="btn btn-download">Download</button>
<button type="button" class="btn btn-upload">Upload</button>
<button type="button" class="btn btn-config">Configuration</button>

To incorporate predefined icons, simply append the btn-icon class to any of the above buttons, and the corresponding icon will be displayed.

<button type="button" class="btn btn-save btn-icon">Save</button>

Note that <input type="button" class="btn btn-icon btn-save" value="Button label" /> is not effective because input fields do not support the pseudo CSS class :after. Thus, it is recommended to use the button HTML element or an alternative instead of input.

To show a button with a generic predefined icon, use btn-icon without specifying a particular class:

<button type="button" class="btn btn-icon"><i class="material-icons">check</i>OK</button>

For a btn-icon button without a background, add btn-link:

<button type="button" class="btn btn-icon btn-link"><i class="material-icons">check</i>Link</button>

Here are some example combinations:

<button type="button" class="btn btn-icon btn-save">Save button with icon and text</button>
<button type="button" class="btn btn-cancel">Cancel button without icon</button>
<button type="button" class="btn btn-icon btn-delete"></button> // Delete button without label, but with predefined icon and colors.
