The grouping of style attributes for some page elements can be found within class selectors. These class selectors, or classes, are identified by a preceding dot in the class title. An example of a style sheet class can be found below.
Any HTML element that utilizes this class will display the text as green, bolded text. The color attribute can be set to explicit colors (Example: red, blue, green), or it can be assigned a hexadecimal color value.
