When you want to style an element with more than one visual property, you include multiple property-value pairs inside a single rule block. Each property is written on its own line, followed by a colon, the value, and a semicolon. For example, you can set the background-color, color, padding, and border-radius all within the same selector’s curly braces. This makes your CSS concise and easy to read.

To make your stylesheets even clearer, you can add comments within your CSS. Comments are useful for explaining the purpose of a rule or reminding yourself why you chose certain values. In CSS, a comment starts with /* and ends with */. Anything between these markers will be ignored by the browser and will not affect your styles.
