Limit amount of text in a div

Let’s say I have a div like this:

<div id=“lots”>
Lots and lots of content
<div>

in the css I do

#lots{
width: 200px;
height: 15px;
}

Now let’s say the ‘Lots and lots of content’ greatly passes a height of 15pixels, I don’t want to display it I want anything that passes 15 pixels to be hidden, how would I do that?

Thanks

overflow: hidden
