Change font inline – Vantage

I would like to change the font (font-family) for select words in a sentence without a line break. I am using Vantage and tried to use custom CSS by using an H5 class, but get a line feed. Likewise with Div. Do you know a way to do this?

CSS:
h5.dancing {
font-family: “dancing script”;
font-size: 2em;
}

On page:

thank you,
