Here is a link to a definition of "em":

In epub parlance it's pretty much the same. Since most epubs are read using mobile readers it is better to stay away from fixed measures. If you specify a fixed indent and the reader increases the font size, the indent will be relatively smaller and look strange.

Here is an example of a minimal paragraph css.
.para {
display: block;
margin-top: 0;
margin-bottom: 0;
text-indent: 1.5em;
}
You can control the line spacing by adding "line-height:X.Xem;" to the above.
Invoked by <p class="para">paragraph text stuff</p>

The "margin" statements gives you single line spacing.

Three times I deleted all the </p> text in the code at the end of the sentence where there was one too many line spaces following and saved the changes but nothing changed.

Since every <p> must have a </p>, maybe Sigil re-inserted them.

I'm new to this stuff myself so if some you old hands correct me, I won't be offended .
