Widget CSS Classes Plugin

Widget CSS Classes gives you the ability to add custom classes and ids to your WordPress widgets

• widget-last: added to the last widget in a sidebar
• widget-odd: added to odd numbered widgets in a sidebar
• widget-even: added to even numbered widgets in a sidebar
• widget-#: added to every widget, such as widget-1, widget-2

Features

• You can specify multiple classes by putting a space between them
• Optionally adds checkboxes with predefined classes
• Optionally adds a text field to add an id to a widget
• Adds first and last classes to the first and last widget instances in a sidebar
