Selectors
sIFR supports the following types of CSS selectors out of the box:
h1h1 > emh1 em.fooh1.foo#barh1#barh1#bar.foo#bar.foo.foo.baz
More selectors can be added, read more in parseSelector.
If you want to use a general selector and more specific ones, make sure the most specific one is replaced first. i.e. 'h1.foo' is higher on the page than 'h1'
