Astero utilizes Ajax technology and local caching for fast loading of weather forecasts that supports a fixed location or user geolocation. Optional search function lets users look up the weather with a city name or zip code, and choose their preferred units! Create stunning weather widgets with animated backgrounds, custom images or a clean and minimalist look easily with the shortcode builder. Scripts and styles are loaded conditionally to minimize HTTP requests, and Html5 caching is enabled to increase loading speed and avoid API call limits. Use as a widget, shortcode, or both!
