If you want it to work for the whole document, you probalby want to replace

p.left {...}

simply with p {}

To do it for a whole section -- I think you mean a whole slide? -- I think
you would want

.left p {...}

in your css file, and to add a property to the containing header like so:

:PROPERTIES:
:HTML_CONTAINER_CLASS: left
:END:

You can add a property easily with C-c C-x p
