how to change the complete UI of login page..?

Hi @murali_mca

The Login Page can be customized by writing some scripts for a new website theme.

The following screenshot may help;

The image must exist in file list.

Create an HTML file named login.html inside your app’s www file.

Frappe will read your app’s login.html file instead of reading the login.html file in Frappe app.

Note:
You also need a login.py file responsible for communicating with the server.

To make simple changes to the login page, copy the contents of the login.html file in your Frappe app and paste it into the login.html file in your app. Edit the parts you want to change Also, in your app’s login.py file, type the command from frappe.www.login import * This will retrieve all the login.py code in your Frappe app (you should be aware of what you’re doing)
