Javascript getBoundingClientRect bounce off edges of screen

I'm creating a landing page that features background text that moves about randomly. I am trying to get the text divs to bounce off the edges of the screen when they hit and to bounce of each other. Unfortunately, I haven't used .getBoundingClientRect() before so I'm a bit lost. Also I am using the GSAP animation platform.

var bgtext = document.querySelectorAll('.text');

function moveText(){

    TweenLite.to(bgtext, 1, {opacity: 1});

    for (var i = 0; i <= bgtext.length; i++) {

        var xPos = Math.floor(Math.random() * 2001) - 1000;
        var yPos = Math.floor(Math.random() * 2001) - 1000;

        TweenLite.to(bgtext[i], 5, {xPercent:''+xPos+'', yPercent:''+yPos+'', force3D:true});

        // var rect[i] = bgtext[i].getBoundingClientRect();
        // var x[i] = rect[i].left;
        // var y[i] = rect[i].top;
        // var w[i] = rect[i].right - rect.left;
        // var h[i] = rect[i].bottom - rect.top;

        // if (x[i] <= 0 || y[i] <=0){

        //  xPos = Math.floor(Math.random() * 500);
        //  yPos = Math.floor(Math.random() * 500);

        //  TweenLite.to(bgtext[i], 5, {xPercent:''+xPos+'', yPercent:''+yPos+'', force3D:true});

        // };
