CSS: Control space between bullet and <li>

I'd like to control how much horizontal space a bullet pushes its <li> to the right in an <ol> or <ul>.

That is, instead of always having

*  Some list text goes
   here.

I'd like to be able to change that to be

*         Some list text goes
          here.

or

*Some list text goes
 here.

I looked around but could only find instructions for shifting the entire block left or right, for example, http://www.alistapart.com/articles/taminglists/

Put its content in a span which is relatively positioned, then you can control the space by the left property of the span.

li span {
  position: relative;
  left: -10px;
}

<ul>
  <li><span>item 1</span></li>
  <li><span>item 2</span></li>
  <li><span>item 3</span></li>
</ul>
