CCS Style to Ensure Flush Lines in Numbered Steps

Here is the output in HRML5

Note on the "a" and "b" steps, the first line is indented and not flush. Also, note on the "1" and "2" steps, the first line is flush with the remaining lines in the step. The goal is to have the text in the "a" ad "b" steps flush for all lines of text.

Need some imput on how to resolve this issue.

Below is style mapping from the CSS file:

p.Step:Sub1 {
                      display: list-item;
                      list-style-type: none;
                      list-style-position: outside
                      margin-left:54pt;
                      margin-right:0.000pt;
                      text-align:"."right;
                      text-align:left;
                      text-indent:-15em;
                          margin-top:8.000pt;
                          margin-bottom:0.000pt;
                          font-family:Arial;
                          font-size:11.0pt;
