# Embeds

## Introduction

&#x20;Rules are directly applied to `<iframe>`, `<embed>`, `<video>`, and `<object>` elements; optionally use an explicit descendant class `.embed-responsive-item` when you want to match the styling for other attributes.

## How to Setup

### **HTML Structure**

```markup
<div class="embed-responsive embed-responsive-16by9">
    <iframe class="embed-responsive-item" src="...." allowfullscreen></iframe>
</div>
```

{% hint style="info" %}
&#x20;You don’t need to include `frameborder="0"` in your `<iframe>`s as we override that for you.
{% endhint %}
