+Some AutoConnectAux APIs specify AutoConnectElement as an argument. There are also functions that returns a pointer to AutoConnectElement. In order to make these interfaces single, AutoConnectElement behaves as a variant type of other elements. Use [reinterpret_cast](https://en.cppreference.com/w/cpp/language/reinterpret_cast) to cast from a variant pointer to an Actual type pointer of AutoConnectElements.

+## Describe custom Web pages with JSON
+
+You can embed custom Web pages written in JSON into AutoConnect without declaring AutoConnectAux & AutoConnectElements in sketches. Custom Web page declaration in JSON can be included in the sketch in advance as the fixed string, or it can be stored in the external file such as SPIFFS for stream loading. You can also load and save AutoConnectElements objects individually.[^1]
