The only way to style a carousel's item/LI is by accessing the html node directly:

.myCarousel li {
width:644px;
}

But if each carousel item contains more LIs, then all LIs end up having a width of 644px.

Trying...

.myCarousel li.yui-carousel-item-selected{
width:644px;
}

...messes up the width calibration of the carousel.

One solution is to add a wrapper and then access the node...

.myCarousel .spotlight .anyWrapper li {
width:auto;
}

Still my concerns are:
1. More markup required by the user,
2. Is it safe to assume users will figure out the solution?
3. Styling a node directly just feels iffy in general.

Maybe add one class to all item/LIs?

Also notice I have to override styles being applied to all LIs inside a carousel to just to get default behavior each time I want to add a list to my carousel. Here's another default style I had to
reset:

.myCarousel .spotlight .anyWrapper li {
width:auto;
display:block;
}

So there's a user convenience as well as a default behavior factor.
