Disney Wiki has over 43,000 pages so has complex portable infoboxes requiring you to copy many parts to get them to work. As you want their look, you could copy their original (pre-portable infobox) template. I have changed your prop infobox to that, using their blue theme to match your wiki colors.
To use with VisualEditor, Template:Prop is stored in Templates.
That may or may not be true in general. However, in this case, both templates were pretty straight forward, self-contained, portable infoboxes. The version you provided is far more complicated than the portable one.
Ok, I do understand what you're trying to say but could you help me put that around the details of the character infobox because I'm not sure if I should put it around the details such as "Personality," and "Appearance"
If you are talking about the CSS and template, no. If you are talking about the content in the template, I am not sure. That depends on the interaction between the various licenses involved with the content.
Look, just wondering on my character infobox, it does this. Like if there's a long word about to hit a line it does this. "Persua" and then finishes the rest of the word on the next line. Just wondering, is there a way to change that, so the words won't show any lines until it's a hypen? If you don't understand what I'm talking about just ask me.
If you are looking for specific CSS that you can copy-and-paste, please provide a link so I can see what you are talking about. All I got from your post was that you are having issues with word wrapping. To that end, I suggest you check out word-wrap and word-break.
Hey, I renamed a character named Rebecca to Plumette and I left a redirect page. But for some reason when I pushed the Rebecca tab, it goes to the redirect page and not the article. If I send you the link, could you fix it?
The issue is that you have chained redirects. The redirect functionality only follows the first redirect; thus landing on a subsequent redirect page. To see a list of chain redirects, use Special:DoubleRedirects.
Before moving forward, I would suggest you consider whether or not having so many redirect pages is really necessary.
If you are concerned with users typing in a specific form of the name and not finding it, consider using SearchSuggest (although there are mixed reviews regarding its success).
If, for whatever reason, you decide you want to keep all the redirect pages, the solution is to have them all point to the most recent name. You can do that by editing the redirect pages. You can read Help:Redirect for more information.
