Buttons
LeptonX uses
Bootstrap Button's
component's latest version.
Use Bootstrap’s custom button styles for actions in forms, dialogs, and more with support for
multiple sizes, states, and more.
Examples
Bootstrap includes several predefined button styles, each serving its own semantic purpose, with a few extras thrown in for more control.

<button type="button" class="btn btn-dark mb-1">Dark</button>
<button type="button" class="btn btn-link mb-1">Link</button>
Button tags
The .btn classes are designed to be used with the
<button> element. However, you can also use these classes on
<a> or <input> elements (though some browsers may apply a
slightly different rendering).
When using button classes on <a> elements that are used to trigger in-page
functionality (like collapsing content), rather than linking to new pages or sections within the
current page, these links should be given a role="button" to appropriately convey
their purpose to assistive technologies such as screen readers.

<a class="btn btn-primary" href="#" role="button">Link</a>

<input class="btn btn-primary" type="button" value="Input" />
<input class="btn btn-primary" type="submit" value="Submit" />
<input class="btn btn-primary" type="reset" value="Reset" />
Outline
In need of a button, but not the hefty background colors they bring? Replace the default modifier
classes with the .btn-outline-* ones to remove all background images and colors on
any button.

<button type="button" class="btn btn-secondary btn-sm mb-1">
Small button
</button>
Active & Disabled States
Make buttons look inactive by adding the disabled boolean attribute to any
<button> element. Disabled buttons have
pointer-events: none applied to, preventing hover and active states from triggering.
Disabled buttons using the <a> element behave a bit different:
-
<a>s don’t support thedisabledattribute, so you must add the.disabledclass to make it visually appear disabled. -
Some future-friendly styles are included to disable all
pointer-eventson anchor buttons. -
Disabled buttons should include the
aria-disabled="true"attribute to indicate the state of the element to assistive technologies.
HTML
<button class="active btn btn-primary btn-lg mb-1" type="button">
<span>Primary button</span>
</button>
<button class="active btn btn-secondary btn-lg mb-1" type="button">
<span>Button</span></button
><br />
<button class="btn btn-primary btn-lg mb-1" disabled="disabled" type="button">

Block buttons
Create responsive stacks of full-width, “block buttons” like those in Bootstrap 4 with a mix of our display and gap utilities. By using utilities instead of button specific classes, we have much greater control over spacing, alignment, and responsive behaviors.
Here we create a responsive variation, starting with vertically stacked buttons until the
md breakpoint, where .d-md-block replaces the
.d-grid class, thus nullifying the gap-2 utility. Resize your browser to
see them change.
You can adjust the width of your block buttons with grid column width classes. For example, for a
half-width “block button”, use .col-6. Center it horizontally with
.mx-auto, too.
Additional utilities can be used to adjust the alignment of buttons when horizontal. Here we’ve taken our previous responsive example and added some flex utilities and a margin utility on the button to right align the buttons when they’re no longer stacked.

<div class="d-grid gap-2 mb-3">
<button class="btn btn-primary" type="button">Button</button>
<button class="btn btn-primary" type="button">Button</button>

<div class="d-grid gap-2 d-md-block mb-3">
<button class="btn btn-primary" type="button">Button</button>
<button class="btn btn-primary" type="button">Button</button>

<div class="d-grid gap-2 col-6 mx-auto mb-3">
<button class="btn btn-primary" type="button">Button</button>
<button class="btn btn-primary" type="button">Button</button>

<div class="d-grid gap-2 d-md-flex justify-content-md-end">
<button class="btn btn-primary" type="button">Button</button>
<button class="btn btn-primary" type="button">Button</button>
</div>
Toggle states
Add data-bs-toggle="button" to toggle a button’s active state. If you’re
pre-toggling a button, you must manually add the .active class and
aria-pressed="true" to ensure that it is conveyed appropriately to assistive
technologies.

<div class="mb-2">
<button
type="button"
class="btn btn-primary"
data-bs-toggle="button"
