Try this instead to select the second DIV,

    var el = document.body.getElementsByTagName("div")[1];
    el.style.color = "green";

You don't use the .className JS ending. Just use this:

var el = document.body.getElementsByTagName("div")[0];
el.style.color = "green";
<div class="box">
        Element1
    </div>

    <div class="box">
        Element2
    </div>

    <div class="box">
        Element3
    </div>

I think you want this:

var el = document.body.getElementsByTagName("div")[0];

adding .className to the end makes el into a string rather than an element.

Also you can omit .body from this is you like, its more usual to just say: 

var el = document.getElementsByTagName("div")[0];
