You don't need to enclose each argument in brackets, you just need to
enclose all arguments in brackets (which is the recommended practice).
start_form_tag(
{:action => 'blah'},
{:class => 'css1'})
works fine.

Subject: Passing inline hashes
I just stumbled across an intresting problem with passing two hashes to
a method -- I was trying to pass inline hashes and ruby interpretted
them as blocks. (Makes sense looking back).
start_form_tag :action => 'blah', :class => 'css1'
This call was putting both values into the first parameter of the method
(a hash), and none in the second one. So I altered it:
start_form_tag {:action => 'blah'}, {:class => 'css1'}
Which of course ruby thinks the {} are blocks and pukes.
To explicitly tell ruby they are hashes, I had to wrap them with ().
start_form_tag ({:action => 'blah'}), ({:class => 'css1'})
Which seems awkward, as most languages use the {} syntax for inline
hashes.
