I like Context if Path /gallery Load A New Theme example "Bartik" Other page load "Omega" Theme
I Install the "Context Condition Theme" Modules But it does not working
What's your recommendation?
Use can use ThemeKey module.
Enable ThemeKey module and its required sub modules, then go to the config page at admin/config/user-interface/themekey
. Here you will see may options for switching the theme.
As you required there is an option path:node_alias
so select this option and also set the value as you want like you say /gallery
and then select the theme you want to enable at this url.
For wildcard path use this setting as you required web/*
:
Property: drupal:path
Operator: =
Value: %wildcard
Property: drupal:path:wildcard
Wildcard: wildcard
Operator: ~
Value: /^web/.*
