XF 2.3 BBcode for html elements within element (div)

[Mr Lucky]

For example I want too do this, where there is one container but several div elements within

<div class="boxcontainer">
    <div class="box">
        Some text that may also include formatting.
    </div>
    <div class="box">
        Some more text that may also include formatting.
    </div>   
</div>

I can do this but my experiments so far requite three lots off BBcode, can it be done with one?

Thanks
