Drupal 7.x

I'm planning to make my first site with Drupal. I'm creating custom theme for it, but how can I do the menu like it is on this site (drupal.org)? If you are on the "Drupal Homepage" page it colors the menu item background to white and if you are not it stays blue.
Maybe I should check the url of the page and then choose the right CSS class?

Please help me. (Sorry if the thread is in the wrong forum.)

Hello all,

Hello, i'm using forum core module (drupal 7) and added a custom vocabulary text field 'field_company'. I want to add to forum table a column 'Company' and display for each forum topic 'company' field. How can i access to my custom field value ?

I have 5 fields in views. 3 of them I display as inline (I checked inline in views options).

So I have:

Title
'One field' 'two field' 'three field'
Body

I'd like to use css for this group: 'One field two field three field'.
I know how use for each, but I don't know how use for all.

All these fields are as span tag. There aren't divs around this group.

I am working in a module upgrade from drupal 6 to 7, most of module is working, but i must be missing something, look at this:
customfilter.module

Use the form FIVESTAR comments rating integrated with unserpoint , now every time that the message of a user is voted (1 to 5 stars) he gains a vote.
The problem is that I wish that you earn respect only if the vote with at least 3 / 5 of stars
