<isw-responsive>

isw-responsive calculates device and orientation according to material design breakpoints and pushes the result to all elementes using isw-responsive-behavior using iron-meta and iron-signals like events.

If there will be an iron-signals 2.0, the element will be updated to use it instead of custom document events.

https://material.io/guidelines/layout/responsive-ui.html#responsive-ui-breakpoints

isw-responsive

Calculates device and orientation from the current screen size.

Use it only once in your app, it will notify all isw-responsive-behavior elements about changes.

isw-responsive

Provides reflectToAttribute properties for css selectors, and events for imperative use.

iron-meta

isw-responsive writes the viewport information to iron-meta, so they are global available via these keys:

  • isw-responsive-device
  • isw-responsive-orientation

iron-signals

Future plans: If iron-signals will get an 2.0 update, the viewport-changed event should be exposed to iron-signals., e.g.:

  • isw-responsive-viewport-changed

Example: Useage with Starter Kit.
