Navigation - highlight current menu tab

[eluser]cinewbie81[/eluser]
$this->uri->segment(1) will get you the current controller name ..

for eg:

url = https://localhost/backup/listing

$this->uri->segment(1) will return u the value 'backup' ..
highlight this 'backup' module use the 1st segment of ur url ..
but i believe there's a better way using CSS ??
