Persian needs some RTL layout work

[incompl]

In position.html, red box is not positioned properly

In position-example.html, float-layout.html , media-queries.html and percent.html, sidebar must be a right-side sidebar, to match with rtl.

In inline-block.html, first example items are float left and not the same as second example. So they must have float:right

In inline-block-layout.html and flexbox.html, sidebar is correctly a right-side sidebar! May be you want to skip previous issue and change this one.
