## Installation

* [npm](https://www.npmjs.org/package/suitcss-components-flex-embed): `npm install suitcss-components-flex-embed`

* Download: [zip](https://github.com/suitcss/components-flex-embed/zipball/master)

## Available classes

* `FlexEmbed` - The root node.
* `FlexEmbed-ratio` - The element that provides the aspect ratio (1:1 by default).
* `FlexEmbed-ratio--3by1` - The modifier class for 3:1 aspect ratio embed.
* `FlexEmbed-ratio--2by1` - The modifier class for 2:1 aspect ratio embed,
* `FlexEmbed-ratio--16by9` - The modifier class for 16:9 aspect ratio embed.
* `FlexEmbed-ratio--4by3` - The modifier class for 4:3 aspect ratio embed.
* `FlexEmbed-content` - The descendent class for the content that is being displayed.

## Usage

Example:

```html
<div class="FlexEmbed">
  <div class="FlexEmbed-ratio FlexEmbed-ratio--16by9"></div>
  <div class="FlexEmbed-content">
    <!-- child content -->
  </div>
</div>
```

You can add custom own aspect ratios. For example, to create a 2.35:1 aspect
ratio:

```css
/**
 * Modifier: 47:20 aspect ratio
 */

.FlexEmbed-ratio--47by20 {
  padding-bottom: 42.55%;
}
```

Alternatively, aspect ratios can be calculated programmatically and the
corresponding `padding-bottom` value applied using an inline style.

```html
<div class="FlexEmbed">
  <div class="FlexEmbed-ratio" style="padding-bottom:{{percentage}}%"></div>
  <div class="FlexEmbed-content">
    <!-- child content -->
  </div>
</div>
```
