CSSklasse
CSSklasse, often referred to as a CSS class, is a fundamental concept in Cascading Style Sheets (CSS) used for styling HTML elements. A class is essentially a label that can be assigned to one or more HTML elements. This label allows developers to apply a specific set of CSS rules to all elements that share that particular class name. Instead of styling each HTML element individually, classes provide a way to group elements with similar visual characteristics and apply styles efficiently.
To define a CSS class, a period (.) is used as a prefix followed by the class name
