Is margin possible for <div> in css?

Question

Can I set a field for a text area?

My wysiwyg editor puts my text in tags <div>instead of providing strings<br />

So, I was thinking giving a <div>margin?

Is this possible in css? And if so, how?

Many thanks.

EDIT: I cannot define divs because it does not receive classes. For example, the editor does this:

<div>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Vestibulum egestas lacus libero, et pellentesque nisl. Cras pharetra nunc sit amet urna vestibulum non ultricies metus malesuada. </div>
<div>Nulla tincidunt, neque at blandit ultrices, massa odio pulvinar est, vel accumsan sapien justo sit amet lorem.</div>

Run code

It looks like this:

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Vestibulum egestas lacus libero, et pellentesque nisl. Cras pharetra nunc sit amet urna vestibulum non ultricies metus malesuada.
Nulla tincidunt, neque at blandit ultrices, massa odio pulvinar est, vel accumsan sapien justo sit amet lorem.

But it should be like this:

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Vestibulum egestas lacus libero, et pellentesque nisl. Cras pharetra nunc sit amet urna vestibulum non ultricies metus malesuada.

Nulla tincidunt, neque at blandit ultrices, massa odio pulvinar est, vel accumsan sapien justo sit amet lorem.
