/*
	make a few css adjustments specifically for Opera.
	
	(definitely not pretty. probably caused by all of the vertical alignment in column 3 of the home page. 
	 I expect it is caused by a line-height discrepancy between the browsers. But we are already requiring js so
	 I have opted for this ugly fix instead of re-engineering the layout of column 3.)
	
	This code is called by a script reference in the head of an html file and it writes 
	in a link to a css override file. 
	This code assumes that all pages that use this script are located in the ROOT DIRECTORY.
