Clearing 4th item

Hi there,

You need to provide something called a clearfix and then select the element with something called an nth child selector.

:nth-child(4);

So here's the CSS you need to clear floats on an element.

selector {
   display: table;
   content: "";
   clear: both;
}

That's a clear fix. Now to clear every 4th item you need to provide the selector that selects every 4th item in sibling elements.

To do this you simply provide the seletor i procises avoce as a pseudo element. http://stackoverflow.com/questions/16948286/selecting-every-4th-div

So you'd use your selector (I'm not sure which one you need precisely, and then use a colon (:) to add the nth child selector to it,

e.g.

selector:nth-child(4) {
   display: table;
   content: "";
   clear: both;
}

Remember to add the peusdo selector to a group of list items rather than their containing element.

Hope this helps :)
