<img-placeholder>

DEPRECATED: This component is based on a very old version of Polymer and is no longer being updated.

Easily insert placeholder images in your HTML pages using Polymer and web components.

Originally by Zachary Jones. Uses Placehold.it for the placeholder images.

Demo

Install

3. Start using it!

   <img-placeholder></img-placeholder>

Options

<img-placeholder> intentionally shadows the spec of the regular HTML <img> so that you can easily convert it to a real <img> tag in the future when you have the final image you want to show.

Attribute	Options	Default	Description
width	integer	256	Width of the image.
height	integer	256	Height of the image.
alt	string	''	Optional. Text to be shown on image.
src	string	''	Optional. Image filename with extension. Used to generate correct image type. Default is a GIF.
