css - How to enable auto indentation in lists and list items? -

i new css, took on someone's css code has:

.. css reset .. ul, ol, li .. {    ..    margin: 0;    padding: 0;    .. } 

however, setting padding 0 disables automatic list item indentation, want indentation, wrote:

<ul style="padding: 10;">     <li style="padding: 10;">         <ul style="padding: 10;">             <li  style="padding: 10;">123</li>         </ul>     </li> </ul> 

padding: 10 not have effect, browser still displays no padding, no indentation.

how auto indentation in place?

friend, 10px not 10 padding value.

 <li  style="padding: 10;">123</li> 

should be

 <li  style="padding: 10px;">123</li> 

cheers,
