<div id="root-container">

        <h1>Content</h1>
        
        And when the body finally starts to let go<br/>
        let it all go at once<br/>
        not piece by piece<br/>
        but like a whole bucket of stars<br/>
        dumped into the universe<br/>
        Whoh! Watcb it go!<br/>
        Good-bye small hands, good-bye small heart<br/>
        good-bye small head<br/>
        My soul is climbing tree trunks<br/>
        and swinging from every branch<br/><br/>
        
        They're calling on me<br/>
        they're calling on me<br/><br/>
        
        Do you think I'm an animal?<br/>
        Am I not?<br/>
        Do you like fur<br/>
        Do you wanna come over<br/>
        Are we captive only for a short time<br/>
        Is there splendor, I'm not ashamed<br/>
        Desire shoots through me<br/>
        Like birds singing<br/>
        (The way you move no ocean's waves were ever as fluid)<br/><br/>
        
        They're calling on me<br/>
        they're calling on me<br/>
        
        I hit the mark!<br/>
        I target moon, I target sky, I target sun<br/>
        Fall down on the world before it falls on you<br/><br/>
        
        Like beggars, like Stars<br/>
        like whores, us all<br/>
        Like beggars, like dogs<br/>
        Like Stars, us all<br/><br/>
        
        Shoot straight for my heart<br/>
        (And when you were near no sky was ever quite so clear)<br/><br/>
        
        Like stars, so small<br/>
        Like us, when we fall<br/>
        Like beggars, like whores<br/>
        Like lovers, Get Up!<br/>
        Get up, too far
