css for form feilds: modify form field sizes

i want to make some form fields bigger. there are several, but for instance the drop downs on boat_data_insert:some of the choices are longer than the form box. also notes on event_insert; the field is varchar 256 but it is a small box to type in. i am sure this is easy, and i have several others i want to modify. i have tried to find the class but not having luck. just cannot find the class(es) to modify. it would be cool if i could modify right at the particular box, rather than change class for all boxes on a page. thanks

You can add a style="" tag to the individual boxes to override the class and set a new width like: style="width:400px;"

thank you. i will post this next one here so i don't clog up your help forum.
1. that worked, and i was able to add height also, but i should have been more specific. if i change height, it all still stays on one line. is there a way to do the same 'one time' entry that will allow the entered text to fill the text box without scrolling?or maybe so it scrolls vertically, much easier to review before submitting that way.
2. on update page attached, when i submit, on the details page, it displays "This record has been removed" and does not update the field.

1) There is no easy way to do this. Select lists will not scroll vertically.

2) There is supposed to be a hidden form element on the update page that appears to have been deleted. You can add it back manually:

<input name="WADAUpdateRecordID" type="hidden" value="<?php echo($row_WADAevent["event_id"]); ?>"  >

1. it is not a select list. line 146
2. thank you. i must have deleted when re-doing link buttons.

You can use a <textarea> field to allow multi-line input in a form.
