 Did you Ever Got into the Trouble of Making a good Looking UI for ESP8266 without having the skills to Build Perfect Webpages?
-EasyUI is an User Interface Library for ESP8266 to Solve this Problem. This Library Uses Light-weight Websockets Protocol for Communicating with Webpage to Control, Make and Update Elements. All Elements are Created in  a Card Type Grid, Where Each Element Stacks aside the other. The Whole webpage is Responsive and Adapts to Mobile Displays.
+EasyUI is an User Interface Library for ESP8266 to Solve this Problem. This Library Uses Light-weight Websockets Protocol for Communicating with Webpage to Control, Make and Update Elements.
