Looking at your posts, a simple copy and paste of the CSS styles and HTML text would have been easier than your Word document.
As it is, I would suggest that you are not error checking your epub. Looking at where you show:
Code:
<p class="Capitular">
<p class="block14">Sofia estava consultando etc.
A <p> tag is not nestable. <p><p></p></p> is not a valid construct.
When I typed the above into an epub in Sigil and added the 2 </p>s, epubcheck threw the following error message:
Code:
Col: 20: ERROR(RSC-005): Error while parsing file: element "p" not allowed here; expected the element end-tag, text, element "a", "abbr", "area", "audio", "b", "bdi", "bdo", "br", "button", "canvas", "cite", "code", "data", "datalist", "del", "dfn", "em", "embed", "epub:switch", "i", "iframe", "img", "input", "ins", "kbd", "label", "link", "map", "mark", "meta", "meter", "ns1:math", "ns2:svg", "object", "output", "picture", "progress", "q", "ruby", "s", "samp", "script", "select", "small", "span", "strong", "sub", "sup", "template", "textarea", "time", "u", "var", "video" or "wbr" (with xmlns:ns1="http://www.w3.org/1998/Math/MathML" xmlns:ns2="http://www.w3.org/2000/svg") or an element from another namespace
If I modified the code to:
Code:
<p class="Capitular block14">Sofia estava consultando etc.</p>
the drop cap showed up. See attached image for what it looked like.
