I am a tad confused. It appears that the classes .calibre, .calibre1, .calibre 2, etc are not standard or am I missing something.
eg
example 1
.calibre2 {
display: block;
font-size: 1.41667em;
font-weight: bold;
line-height: 1.2;
margin-bottom: 0.83em;
margin-left: 0;
margin-right: 0;
margin-top: 0.83em
}
example 2
.calibre2 {
display: block;
margin-bottom: 1em;
margin-left: 0;
margin-right: 0;
margin-top: 1em
}

I am cleaning up several books and was trying to find similarities in order to streamline the process.

Understanding how calibre names the classes might help (I hope) reduce the time required
