Module development and code questions

hi,

is there a mechanism to use css tags sidewide.
I think of something like placing a style.css in my sites/ directory.
Or do i have to edit the style.css file of every theme.

I am developing an application on drupal and developing custom modules using form api. I have my own theme implemented which gives a specific look to my application. My roadblock is, I want to implement drupal comments functionality to every saved record listing. I wish to call the comments form using ajax i.e. I wish to implement this without refreshing the page. Can anyone please throw some light on this as to how this can be achieved. Your inputs will be greatly appreciated!!!

Hi,

Im new on this Drupal world. I searched all this site finding an answer, and nothing. Thats because i need a better answer cause i don't understand too much Drupal. Dont get angry.

The thing is. Im trying to use the jscalendar that i readed is attached to Drupal 5. I activated the module.
Then, i tried to use for this: I need a textfield and a calendar at his side. When clicked, the calendar must Pop-up and the user need to be able to select a date, and that date goes to the text field and everybody happy. This is a page, not a block.

I readed about this code in a example:

$form['date'] = array(
    '#type' => 'textfield',
    '#attributes' => array('class' => 'jscalendar'),
  );

I copied it to my code, and nothing happens. It saids (the readme) that all u need is give the class "jscalendar" to a textfield. And I did this (this input on a form in html):

<input type="text" name="date" class="jscalendar"/>

And nothing happens.

Then, I tried thousands of things:

Printing the $form
Printing the $form['date']
Button with that class
Etc

And nothing happens.

So, im writing this and boring you. But i need this...
please, i need a super example. One with the php, the html... all. Cause i got the $form, but don't know how to call it. it says "array". And sometimes i can see nothing... well, thats it.

Maybe I'm not doing something correctly, or don't have some program/module, but it's been happening a little too much lately that a visitor would go to my website and in the logs I would see something like this: page not found 2007-03-12 07:55 taxonomy/term/6/0/feed Visitor. I don't quiet understand what's happening, but I see Page Not Found, I know that I've enabled the RSS feeds, and my head just starts to itch a little.

anyone have any tips on how to do this? i'm not a programmer by any means and i'm having trouble hacking something together.

what i'm trying to accomplish is return a list of a user's 'bookmarks' as determined by the 'views bookmarks' when viewing their profile.

here's the code that i'm starting with-
