I have a large container with 7 smaller containers inside
<div id="big_div">
<div>a</div> <div>a</div> <div>a</div>
<div>b</div> <div>b</div> <div>b</div><div>b</div>
</div>
Is there a way to arrange the 7 containers in two columns, one with 4 and the other with 3 elements, without modifying the HTML, possibly using nth_child?
#big_div{
}
#big_div div{
}
