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.
The chosen width and height for an IFrame embed is converted into a ratio which is used to scale your embeds across different devices.
