Adding active states to the Navigation

I am wondering :
Why do we need to add $section = null to index.php ?
When $suggest variable doesn't exist in index.php file , none of the link should be underlined , but instead all the links are getting underlined.
Why?

Thanks

Hi Aakash,

It is because the server sees the value as true, when we don't specify the $section value to null / false in this case. So when not defining the section to be "turned off" it will automatically set the variable to true and insert the " on" text for the CSS class.

Hope this helps you :)
