The only thing I could figure was that ADE did not like the CSS taken from the HTML file. Rather than extracting the Style Sheet from the HTML and saving it as main.css, I created my own dummy css with only a comment included and then loaded Sigil. The file came up with no formatting.
I then loaded the following statements one at a time, testing with ADE after every entry.
Code:
body{
margin-left: 15px; margin-right: 15px;
}
p {
margin: 0; padding: 0 0 5px 0; text-indent: 1.5em;
}
h1, h2, h3, h4, h5, h6 {
margin: 0; padding: 0 0 5px 0; text-align: center;
}
a:link {
COLOR: #000000;
}
ADE displayed everything OK. I guess that means that all Style Sheets are not equal and to avoid those in the PG files. Learning can take a while.
