General tips: Look at the code

That determines the S&R least likely to do damage
Do you have a <span class or an <i ?

Single step Replace (Next), not 'Replace all' until you are ABSOLUTELY sure there are no exceptions

Example of a sentence:

<p class="calibre1">This is a sentence.</p>


To add italics to the words "a sentence," add one of the following sets of codes:

<p class="calibre1">This is <i class="italic">a sentence.</i></p>

-or-

<p class="calibre1">This is <span class="italic">a sentence.</span></p>

Then add the following code into your stylesheet.css file:

.italic {
font-style: italic;
}
