The badges provided by all app store providers just don't play well together with their varying typography and different sizing. Only Apple provides a proper SVG source for their badge, Google doesnt even provide a retina bitmap asset.
On top of that, using svg or png assets makes localization a pain unless you want to manage multiple assets per language.
So let's make them all visually unified, infinitely scalable, with pure text for easier localization and some web interaction styles. And while were at it: different sizes with the same markup by using some modifier classes.

# Styling
Lets be honest, Google, Amazon & Microsoft created just slight variations of the badge style established by Apples App Store badge. So its only natural to unify all badges by leaning more to Apples style in terms of typography. Apple uses Myriad Pro in their original badge which isnt available for free web usage.
So all buttons are just set in Apples San Francisco UI font with this funky font stack:
```css
.badge {
font-family: system, -apple-system, '.SFNSDisplay-Regular', 'San Francisco', 'Helvetica Neue', 'Helvetica', 'Arial', sans-serif;
}
```
The first three values are grabbing the system installed version on OS X & iOS, the `San Franciso` value shamelessly references the `@font-face` imported files from Apples S3 account and if all that fails, the badges fall back to either Helvetica or Arial.
Because of varying copy resulting in different badge widths, the only way to make them unified when they are stacked on top of each other, like in a mobile layout, was to make all of them the width of the widest one. This is [defined as a variable in the Stylus source](https://github.com/kremalicious/appstorebadges/blob/master/src/styl/_variables.styl#L12) and set as `min-height` so the badges can grow, like with bigger font sizes or because of localization.
# Usage
Install with npm:
```bash
npm i appstorebadges --save
```
Or install with Bower:
```bash
bower install appstorebadges --save
```
Or just directly link to the css file in the [GitHub repo](https://github.com/kremalicious/appstorebadges):
```html
2015-09-14 00:28:07 +02:00
<link rel="stylesheet" href="https://rawgit.com/kremalicious/appstorebadges/master/dist/appstorebadges.min.css">
2015-09-13 22:20:58 +02:00
```
## HTML Markup
This is the basic markup for all badges:
```html
<a class="badge" href="#">
<svg class="badge__icon">[…]</svg>
<span class="badge__text">Download on the</span>
<span class="badge__storename">App Store</span>
</a>
```
Only the icon and the copy change for each badge. To be able to style modify all colors, including the icon color easily with one variable change, using the SVG assets as `background-image` within `:before` or `:after` content wasn't feasible. So inline SVG it is, which allows easy styling via CSS.
For maximum browser compatibility and simplicity, I just inlined the icon assets in all markup blocks. In a production environment you should create a sprite from them, reference them with the SVG `use` element and polyfill with [svg4everybody](https://github.com/jonathantneal/svg4everybody).
## Size Variations
Just drop those modifier classes on the `badge` base element:
- `badge--small`
- `badge--tiny`
