Re: set line spacing to 0 for images

Yes, you can activate CSS for specific pages, but there may be a better 
way.

Create a file pub/css/MyGroup.MyPage.css and it will be loaded when a 
visitor opens the MyGroup.MyPage page.

However there may be a better way: just add to your local.css styles for 
specific classes of elements:

   .zero-line-height {
     line-height: 0;
   }


Then in the wiki page, wrap your images in a division block of the same 
class:

    >>zero-line-height<<
    Your image links here
    >><<

Note that some email clients may wrongly format the above lines like 
replies.

The first line is ">>zero-line-height<<" and the last line is ">><<".

Enabling line-height for the specific block will allow you to have some 
normally formatted text above and below the images.
