[CSS] Indent every other line?

I’m making up a quick page for an English class project, and basically its a poem that I like with the page reflecting elements of the poem, conveying colors and whatnot. Every other line of this poem is indented, to indicate rhyme pattern, and I was wondering if anyone knew a way to indent every OTHER line in a block of text?

I know you can indent the first line of every paragraph, and do many other interesting font manipulations through CSS, but I’m not really sure about indenting every other line. Thanks for the help in advance.
