css - Targeting li elements? -

i have:

<ul>  <li></li>  <li></li>  <li></li>  <li></li>  <li></li> </ul> 

i want add different width each li.

i don't want inline.

how can target each li using css2 (not css3)?

is there way or need give each li class name?

thanks

you can use comb css have add class each li in css e:g-

li {} li + li {} li + li + li {} li + li + li + li {} li + li + li + li + li {}
