Code poetry for #Valentine.

You're like <html>, there's structure thanks to you.
I want to nest your tags, I hope you love me too.

Or maybe... You're more like CSS. But which selector should I choose?
You're both .classy and #unique, so either way I lose.

I guess you're a bit of everything, maybe some javascript as well.
Because you affect my behavior, I love you more than code can tell.

Though my overflow is getting visible, your <body> still looks fine.
Can I repeat-x with you tonight, my sweet sweet Valentine?
