Make exponent style in Riche Text field I want to provide an easy way to make exponent style text in the Redactor field type.


Is there a Redactor plugin to do that?  

If no what is the best way to handle that?  

1/ HTML superscript tag  

&lt;p&gt;This text contains &lt;sup&gt;superscript&lt;/sup&gt; text.&lt;/p&gt;

or
2/ CSS custom Redactor class  

.sup { 
    vertical-align: super;
    font-size: smaller;
}
In craft/config/redactor you can either add your own setting file, or edit one of the ones already there. If you add the following JSON:

"formattingAdd": [
  {
    "tag": "sup",
    "title": "Superscript"
  }
]


You will have access to a Superscript choice under the Formatting buttons dropdown menu. This will wrap the selected text in a &lt;sup&gt; tag.

While I'm not sure if this is the correct way of adding stuff like this, I just tested it and it does work.
