1 <p>The list of properties and values can be found inside the curly braces of the CSS rule. “Property-value” pairs are separated from each other by a semicolon, and the property is separated from its value by a colon. The property determines which appearance characteristic we want to change, and the value determines how it is changed. Recall the following example again:</p>

2 .feature-kitten { padding-top: 60px; /* Top padding */ background-image: url("img/bottle.svg"); /* Background image */ }<p>In the example the padding-top property is assigned the value 60px, whereas the background-image property is assigned the value url("img/bottle.svg"). As a result, this CSS rule assigns a top padding and background image to all elements with the feature-kitten class.</p>

3 <p>You can set the display parameters for any tag using CSS, such as the width and height, margins, font color and size, background, and so on. Every time we add a new property or change its value, we change something on the page. Let’s try to add a few new properties and see how that changes the blog page.</p>
