Idea is pretty easy. This

<body dir="ttb">  ... </body>

will set :ttb flag for each child of the body element.

Default styling of :ttb elements may look like this:

p:ttb
{
  direction: ttb; /* character flow */
  flow: horizontal; /* block flow */
}

If you have something like

<span class="number">100</span>
inside that paragraph you can say
either

p:ttb span.number
{
   direction:ltr;
   display:inline-block;
}

Or you can simply let it to use default direction:
p:ttb span.number
{
   direction:ttb;
}

So to switch direction will be
a matter of changing @dir from "ttb"
to "ltr" on <body> element.
Quite easy if you would ask me. No?
