can you put two classes in one code example

Example 1: 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 2: 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>
