CSS List Styling Not Lining Up - css

Question

Trying to get these list headings to line up correctly, but I can't figure out the justification to get it to line up. Trying to style it like the second one but those bold tags are pushing it down a line.
<div class="block">
<ul class="toc partThree">
<li><b>39:</b>Maintaining This Diet</li>
<br/>
<li><b class="parts">Part 3A:</b><a class="partslink" href="#"> About Fruit Consumption</a></li>
<li><b>40:</b>Ideal Fruit-combinations</li>
<li><b>41:</b>Fruits To Go</li>
<li><b>42:</b>Salads & Shakes</li>
<li><b>43:</b>Fruits In General</li>
<li><b>44:</b>About Consuming Nuts</li>
<br/>
<li><b class="parts">Part 3B:</b><a class="partslink" href="#"> About Consuming Animal Food</a></li>
<li><b>45:</b>About Fresh Raw Fish</li>
<li><b>46:</b>About Fresh Raw Egg Yolk</li>
<br/>
<li><b class="parts">Part 3C:</b><a class="partslink" href="#"> The Most Important Section of This book</a></li>
<li><b>47:</b>Remember That...</li>
<li><b>48:</b>The Rules</li>
<li><b>49:</b>The Obstacles</li>
<li><b>50:</b>Cravings</li>
<li><b>51:</b>Traps</li>
<li><b>52:</b>How To Pick Munch-foods</li>
<li><b>53:</b>Protein Contents</li>
<li><b>54:</b>Single Munch-food Items</li>
<li><b>55:</b>Munch-food Meals</li>
</ul>
</div>
Here is the CSS:
.toc{
list-style:none;
font-size: 15px;
}
.toc li{
margin:0 0 0 10px;
width: 220px;
overflow:hidden;
font-size:13px;
font-family:Arial;
}
.toc b{
float:left;
padding: 0 4px 0 0;
font-weight:bold;
}
.toc a{
float:left;
width:191px;
padding:0 0 0 0px;
color: black;
text-decoration:none;
}
.toc a:hover{
color: rgba(0,0,0,.8);
text-decoration: underline;
}
b.parts{
}
a.partslink{
}

Made some adjustments, particularly removing floats. This is assuming you don't use the suggestion above of the counter-reset (although with that you'd have to restructure a lot of your HTML it seems).
the trick I used here is to add a padding-left to the li's that are title (add a class .title) then using a negative text-indent to wrap back the first line, but allow the second one to keep the padding. The only downside here is the need for a manual width on the padding/indent values, but it achieves the look you want.
