I think I found a number of errors in the Development Documentation.
http://expressionengine.com/docs/development/reference/display.html
In div, qdiv, span, span_c, and qspan:
The first variable is called ‘style’ and description says ‘Description: Returns opening XXX tag with style style.’
This does not effect the attribute style, it is referencing the elements class.
Also, on qdiv the example would be incorrect too:
// Returns <div [removed]>Email Address</div>
Should be:
// Returns <div class=“menuHeading”>Email Address</div>
I found this while trying to change the style and could not figure out what what the problem.
