Is margin possible for a <div> in css?

Question

Is it possible to define a margin for a text area?

my wysiwyg editor places my text within <div> tags in stead of giving linebreaks <br />

So i thought giving the <div> a margin?

Is this possible in css? and if yes how?

Many thanks.

EDIT: I can't define the divs because it gets no classes. For example the editor makes it:

<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>

This looks like:

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 needs to 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.

You can change the margins of all <div>s in a container by writing

.MyContainer div {
    margin: 42px;
}
