Well, I have the following situation:
<div class="corpo">
<div class="esquerda"></div>
<div class="meio"></div>
<div class="direita"></div>
</div>
I need to add a new div called "all" and inside it I need to have the "left, right, middle" divs. That is, it has to look like this:
<div class="corpo">
<div cass="tudo">
<div class="esquerda"></div>
<div class="meio"></div>
<div class="direita"></div>
</div>
</div>
How do I do with javascript?
