Not sure what you are exactly doing with that but you could probably simplify it to:
p.normalcentreblock {
font-family: "Times"; <-- unless you are embedding fonts, it's not really needed, or use serif
font-weight: normal;
font-style: normal;
font-size: 1em;
<-- 1 em is normal font size, not really needed normally
line-height: 1.25em;
<-- is this really needed?
text-indent: 0em;
<-- only needed if you already indented the p tag
text-align: center;
margin: 0em;
<-- not needed unless you set the margin bigger in the p tag
}
<-- closing MUST have this, did you just forget to copy/paste or is it missing?
normally I do this:
p {
font-family: serif;
font-weight: normal;
font-style: normal;
font-size: 1em;
text-indent: 1em;
text-align: justify;
padding: 0;
margin: .2em 0 0 0; /*gives a margin of 20% of line height at the top of the paragraph and nothing for right/bottom/left margin */
}
.centertext {
text-indent: 0;
text-align: center;
padding: 0;
margin: 0;
}
then you would have for code:
<p class="centertext">Center this text...blah blah blah</p>
<p>this text is just a normal paragraph and not centered</p>
