How To Display It Twice, But Say It Once?

hi-yo

is there a way two divs can display the same text, where the text appears only once in the html?

or, is there a way to make a div mirror the contents of another div, without explicitly typing those contents twice into the html?

or, is there a non-javascript way to dynamically copy text from one element to another?

this does not have to be a css solution, it might be plain html.

thanks!
