Attributes

Attributes	Type	Default	Description
disable-sources	Boolean	false	disable-sources can be used to deactivate the media query checks when aofl-picture loads. It is useful for cases where the desktop version of the app is not responsive.

<aofl-img> embeds an image into the document. It behaves similarly to <img> with the addition of lazy loading images as they scroll near the visible area of the screen. The current formula is 2x height or width. In addition to this <aofl-img> can be combined with <aofl-picture> and <aofl-source> to provide different images for different display sizes.

Examples

Usage

<aofl-img src="path/to/image" width="100" height="100" alt="image description"></aofl-img>
