Let's go to the problem:
I have the following code:
<span id="título">teste1</span>
<div id="div_scroll">
<div id="dv1">teste1</div>
<div id="dv2">teste2</div>
<div id="dv3">teste3</div>
<div id="dv4">teste4</div>
...
</div>
Assuming you have many test divs in there and the div id "div_scroll" and the div id 'dv1' is the top. I would like when to scroll down or scroll the div div "div_scroll" and when each div id "dv?" get to the top, play the text inside it for the spam id title. I researched and found some plugins that do this. But I believe you have some simpler way to do that.
