How can I apply styles to multiple classes at once?

Question

I want two classes with different names to have the same property in CSS. I don\'t want to repeat the code.

Answer 1

If you use as following, your code can be more effective than you wrote. You should add another feature.

.abc, .xyz {
margin-left:20px;
width: 100px;
height: 100px;
} 

OR

a.abc, a.xyz {
margin-left:20px;
width: 100px;
height: 100px;
} 

OR

a {
margin-left:20px;
width: 100px;
height: 100px;
}
