Installation

Add it directly to your webpage using a link tag, thanks to :

``html

`

or install it with npm:

`bash
npm i keyboard-css
`

with yarn:

`bash
yarn add keyboard-css
`

Usage

According to W3C, the kbd element represents user input (typically keyboard input, although it may also be used to represent other input, such as voice commands).

The main purpose of Keyboard CSS is to enhance look and feel such kbd elements, but it can also be used with button and a elements, for better interactivity (like simulating click).

$3

You just have to add a single class to kbd, button or a to apply the related styles, i.e. kbc-button

#### Usage with kbd

When .kbc-button is used with kbd element, font-size and line-height is inherited from parent for better accessibility.

`html


Press / to search this site.

Press Ctrl + Shift + R to re-render this page.

`

!kbd

#### Usage with button and a

When used with button and a elements, it starts supporting interactions.

`html
K
K
`

!.kbc-button

$3

To remove surface border, simply add no-container class.

`html
K
`

!.kbc-button.no-container

$3

Total 5 sizes are available. You can add respective class to see the effect.

> Sizing works with button and a elements, and not kbd element.

| Size | Use case | Class |
| ----------------- | ------------------------------------------- | ----------------- |
| Extra-extra Small | In inputs, like searchbox | .kbc-button-xxs |
| Extra Small | In links, like footer or credit | .kbc-button-xs |
| Small | Same as above, but for more prominent cases | .kbc-button-sm |
| Large | In banners or jumbotrons | .kbc-button-lg |

`html
XXS
XS
SM
MD
LG
`

!kbc-button sizes

$3

> States work with button and a elements, and not kbd element.

Like all buttons, this also have 4 states: :hover, :focus, :active, and :disabled. You can add classes with same state name to see it statically.

`html
Hovered
Focused
Activated
Disabled
`

!.kbc-button states

$3

Colors are inspired from Bootstrap theme colors.

`html
Default
Primary
Secondary
Success
Danger
Info
Light
Dark
`

!.kbc-button colors

Usage with Javascript

You can do a whole bunch of other stuff with Keyboard CSS when you combine it with Javascript. A simple example:

`javascript
const element = document.querySelector('.my-element');
element.classList.add('kbc-button', 'kbc-button-dark');
`

You can also bind keyboard events:

`html
K
`

`javascript
document.addEventListener('keydown', (ev) => {
const key = ev.key;
const element = document.querySelector(
'[data-keyboard-key="' + key.toUpperCase() + '"]'
);
element.classList.add('active');
});

document.addEventListener('keyup', (ev) => {
const key = ev.key;
const element = document.querySelector(
'[data-keyboard-key="' + key.toUpperCase() + '"]'
);
element.classList.remove('active');
});
`

Advanced Configuration Options with SASS

I have used sass to create this build. Mostly, everything is handled through sass variables, so you can easily override the defaults, thanks to !default flag.

$3

You can check all the variables at _variables.scss file.

$3

To change the default base font-size of button and a elements, to 20px, you can do like below:

`scss
// assuming you have already done: npm i keyboard-css

// define variables first
$kbc-font-size-base: 20 / 16 * 1rem;

// and then import
@import "path/to/node_modules/keyboard-css/dist/scss/main";
`

or with new @use rule, you can achieve the same using below code:

`scss
// assuming you have already done: npm i keyboard-css

@use "path/to/node_modules/keyboard-css/dist/scss/main" with (
$kbc-font-size-base: 20 / 16 * 1rem
);
`

$3

You can also introduce your new size:

`scss
// add size in $kbc-btn-size-map
$kbc-btn-size-map: (
"xl": (
"padding-y": 0.75rem,
"padding-x": 1.25rem,
"font-size": 1.5rem,
"line-height": 1.5,
"depth": 11,
"after-border-width": 0.125rem,
"after-adjust-x": -0.125rem,
"after-adjust-y": -5,
"after-border-radius": 0.5rem,
),
);

// and then import
@import "path/to/node_modules/keyboard-css/dist/scss/main";
`

And then use it in HTML:

`html
XL Button
`

$3

Depth is calculated and applied as multiple shadows. To increase/decrease it, you can change respective variables:

`scss
$kbc-kbd-depth: 4;

// and then import
@import "path/to/node_modules/keyboard-css/dist/scss/main";
``
