Burning or pain during urination is typically caused by inflammation of the urethra or bladder. In women, inflammation in the vagina or in the region around the vaginal opening (called vulvovaginitis) can be painful when exposed to urine.
CSS Class Names: Applying Styles to Individual Survey Questions. CSS Class Names allow you to set up a CSS Class on a specific question (or action) that you can then apply CSS to in your survey's theme settings. More technically speaking, a class is a text string that is added to the question's outer-most div that you can then use to apply CSS to anything inside the question.
In object-oriented programming, a class is an extensible program-code-template for creating objects, providing initial values for state and implementations of behavior. In many languages, the class name is used as the name for the class, the name for the default constructor of the class, and as the type of objects generated by instantiating the class; these distinct concepts are easily conflated. When an object is created by a constructor of the class, the resulting object is called an instance of the class, and the member variables specific to the object are called instance variables, to contrast with the class variables shared across the class.
