If you're using respone.menu to build your menu and in line with
http://www.web2py.com/book/default/search?search=response.menu
you could replace the second item (the boolean value)in the tuple with the
check (request.function=='index') where index is your active page.
In this way web2py automatically add to li tag (your menu tab) the
class="web2py-menu-active". So in .css file you can customize it.
For example (I'm using default w2p application "welcome"):
### in menu.py (welcome app models folder) ###
response.menu = [
(T('Home'), False, URL('default','index'), [])
]
becomes
response.menu = [
(T('Home'), (request.function=='index'), URL('default','index'), [])
]
### in layout.html (welcome app views folder ###
change this
{{=MENU(response.menu,_class='sf-menu')}}
to
{{=MENU(response.menu,_class='sf-menu',li_active="tab_highlighted")}}
li_active allows to change default class "web2py-menu-active" to your
preference. In the above example "tab_highlighted".
### in base.css (welcome app static/css subfolder)
append the css rule
.web2py-menu-active a, .tab_highlighted a{color:red}
