Hi. I hope we understood your question which is a bit vague.
You can embed an HTML page into your code as we have done in this project: Web based control and monitoring with PIC microcontroller.
You can read this article to learn more how to code an simple HTML page: Creating Web pages using HML.
make sure all your code especially HTML is not big enough for this chosen PIC.
Why do you need to use ENC28J60 which provide a wired based Ethernet connection with ESP8266 which is wireless(WiFi)?
