Question
How can the same properties be defined for different elements without repeating them again and again? Explain with an example?
Answers
In order to specify the same style properties for multiple elements in css we can make use of class. Class in general are a group of of instances of the same elements to which the same style can be assigned or it can be a group of different instances to which a common style can be assigned.

For Example:

CSS code
P.class1 {color: red} /* defines a class of P selector */
P.class2 {color: blue} /* defines another class of P selector */
.class3 {color: green} /*this class can be used with any element*/
