Google and overflow

Hello,

I asked a question about the css and divs.
If I created a div with style overflow:
div.name {
height: 20px;
width: 500px;
overflow: auto;
}
In my html page, I use the div with 300 to 400 words to increase the number of words in my page without the visitor is see it.
Google penalizes this method?
Thank you for your feedback.

I have a website on Page #1 of Google doing this. Seems fine to me

Thanks !
It will be fine

it will show differently to other browsers too
