Notice the difference in this set of rules
Original:
<p class="st"><b>“Bearing Thorough Witness” About God’s Kingdom</b></p>
p.st, .document .ct {
font-family: "Arial", Helvetica, sans-serif !important;
font-size: 1.25em;
text-align: center;
line-height: 1.1em;
margin-top: 0.5em;
margin-right: 0em;
margin-bottom: 1.5em;
margin-left: 0em;
-webkit-hyphens:none;
}
The AZW file:
<p class="
st2"><a class="pcalibre1 pcalibre2 pcalibre pcalibre3 calibre5" id="page3"></a><b class="calibre4">“Bearing Thorough Witness” About God’s Kingdom</b></p>
.st2 {
-webkit-hyphens: none;
display: block;
font-family: "Arial", Helvetica, sans-serif;
font-size: 1.29032em;
line-height: 1.2;
orphans: 2;
text-align: center;
widows: 2;
margin: 0.36em 0 1em
}
The other styles don't seem to have a direct impact on the font-size in the AWZ they are just margins, bold, color etc.
