I'm sorry, but it seems you need to master some basic HTML/CSS first before tackling this sort of thing. Sigil can't really help you in this regard until you understand those underlying concepts first.

Also, please consider starting new threads for your questions. I can appreciate that you're trying to use the search function to find relevant threads, but unless those threads are fairly recent, just start a new one. Threads like this one were made when Sigil was an entirely different program. There's also no guarantee that the people you're quoting/asking are even around to answer any more. So if the thread is more than a few months old, please consider starting a new one for your question. And please take the advice of others to become familliar with some basic HTML/CSS before tackling some of these more advanced subjects.
