title_body: Moon+ Reader -- what kind of CSS support? formatting tips? A friend recommended Moon+ Reader for android and I was initially impressed by all the features and controls. 
  
  Then I checked how my own published books render in Moon+. I saw lots of weird things. If it matters, I'm on Android 4.21 for one device and Android 4.1 on my Nook HD+ tablet. 
  
  For example, I formatted a play epub which involved lots of hanging indents and centered paragraphs and verse, none of which seemed to render correctly. This play rendered correctly on ibooks, kindle, ADE and nook, but it seems that Moon+ Reader seems to disable css completely. 
  
  In options --> Miscellaneous, I toggled Disable CSS styles and checked "SHow "Preview with Publisher Formatting" button. 
  
  But it seems to make no difference. I see almost no publisher css except for bolds and italics. 
  
  I'm guessing that Moon + just doesn't support a lot of CSS and that "Preview with Publisher Formatting" just doesn't work.  If that's the case, so be it, but I find it hard to believe. Also, I would appreciate any online references to CSS support for each  ebook software. Maybe moon+ doesn't have a lot of mindshare, but I find it hard to believe that I'm the only one to notice these deficiencies. 
  
  This thread http://www.mobileread.mobi/forums/showthread.php?t=194146&amp;page=11 seems to confirm that Moon+ Reader disables publisher defaults by design, but the setting to change that doesn't appear to do anything as well.
upvoted_answer: There is now a setting in MoonReader to disable publisher's CSS. But even when it's not checked, not all CSS is supported.
  I've tested multiple Android Epub readers with a bilingual epub I made, where the two languages are distinguished by the background colour and the font style (the second language is in italics). Only the Gitgen Epub reader displays the background color and the font style properly.
  According to my tests, these Android epub readers support font styles (bold and italics) but not background color:
  
  Prestigio
  Moon Reader
  Pocketbook
  Mantano
  UB Reader
  
  FB Reader did not even show italics.
  I applied the CSS by selecting the class, using !important.
