There's this HTML element meant for marking up keyboard keys named `kbd`. Obviously it can be styled with CSS so why not use it to make those elements look a bit more like hardware or the iOS and Android software keys.
The above picture might be blurry depending on the device you're using so here's a live rendered demo:
<kbd>Light</kbd> <kbd class="dark">Dark</kbd> <kbd class="ios">iOS</kbd> <kbd class="android">An</kbd> <kbd class="android dark">dro</kbd> <kbd class="android color">id</kbd>
They are completely styled with CSS3 so they're sharp on all screens no matter how high the dpi. Have a look at the [full demo](http://lab.kremalicious.com/kbdfun/) or grab the project folder with the CSS & LESS files from GitHub. The code is under the MIT license so you're free to use it in any personal or commercial project.

<a class="btn btn-primary icon-compass" href="http://lab.kremalicious.com/kbdfun/">Demo</a>
<a class="icon-github btn" href="https://github.com/kremalicious/kbdfun/">Github</a>
</p>
## Usage
### CSS
Just drop in the `kbdftw.css` in your `head`:
```html
<link rel="stylesheet" href="kbdfun.css" />
```
If you want to use the Android key style, include roboto.css before:
```html
<link rel="stylesheet" href="roboto.css" />
<link rel="stylesheet" href="kbdfun.css" />
```
You also need to add all the Roboto font files from assets/fonts to your project.
### LESS
There're some variables in the `kbdfun.less` file you can customize.
For the Android style, there's `roboto.less` as include at the end. But the font files won't load unless you uncomment the `.font-roboto` line in kbdftw.less. This is to make sure, users won't download all the font files if you don't use the Android style.
### Markup
The default styling are light keys with Lucida Grande as font:
```html
<kbd>Q</kbd>
```
becomes <kbd>Q</kbd>
Add a dark class to get the dark keys:
```html
<kbd class="dark">Q</kbd>
```
becomes <kbd class="dark">Q</kbd>
Adding an ios or android class gives a replica of those system keys. Android uses three different colors on the default keyboard.
```html
<kbd class="ios">Q</kbd>
```
becomes <kbd class="ios">Q</kbd>
```html
<kbd class="android">Q</kbd>
```
becomes <kbd class="android">Q</kbd>
```html
<kbd class="android dark">Q</kbd>
```
becomes <kbd class="android dark">Q</kbd>
```html
<kbd class="android color">Q</kbd>
```
becomes <kbd class="android color">Q</kbd>
I've let the default `display: inline` intact so all padding on the `kbd` elements won't affect the line-height of the surrounding text. This leads to problems when you want to use them over multiple lines so just make them `display: inline-block` in this scenario.
Pro Tip: if you want to replicate all Mac keyboards after 2003 you have to get VAG rounded for the font.
