add multiple css classes to div code example

Example 1: css multiple classes

//HTML Code
<div class = 'firstClass secondClass'></div>

//CSS Code
.firstClass.secondClass {
  
}

Example 2: css change multiple classes

.objectOne, .objectTwo { /* We will now both be changed */
	margin: 0 auto; 
}

Example 3: css assign multiple classes to one element

To specify multiple classes, separate the class names with a space,
e.g. <span class="classA classB">.
This allows you to combine several CSS classes for one HTML element.

Example 4: more than one class in div

<!-- You can use multiple classes per element if you simply put spaces between the names: -->

<div class="c1 c2"> This div has two classes </div>
