<li>Requires <a href="https://getbootstrap.com/" rel="nofollow ugc">Bootstrap</a> 3.2 or later</li>
<li>This responsive widget resizes with its container</li>
<li>With the <a href="https://make.wordpress.org/core/2017/05/26/media-widgets-for-images-video-and-audio/" rel="nofollow ugc">Video widget</a> in WordPress 4.8 and later, this widget is less necessary for videos</li>
<li>Though this widget still works with videos, the <a href="https://make.wordpress.org/core/2017/05/26/media-widgets-for-images-video-and-audio/" rel="nofollow ugc">Video widget</a> displays well in many <a href="https://getbootstrap.com/" rel="nofollow ugc">Bootstrap</a> themes</li>
<li>But this widget also supports embeds like <a href="https://www.slideshare.net" rel="nofollow ugc">SlideShare</a>, <a href="https://speakerdeck.com" rel="nofollow ugc">Speaker Deck</a>, <a href="https://spotify.com" rel="nofollow ugc">Spotify</a>, and <a href="https://soundcloud.com" rel="nofollow ugc">SoundCloud</a></li>

<p>Fillet adds a new IFrame button to the toolbar in the WordPress visual editor. By using a <a href="https://codex.wordpress.org/Shortcode" rel="nofollow ugc">shortcode</a>, it allows for safer, responsive and future proof embeds.</p>
<p>The chosen width and height for an IFrame embed is converted into a ratio which is used to scale your embeds across different devices.</p>
