Typo in prosilver posting_editor.html
https://github.com/phpbb/phpbb/blob/develop-ascraeus/phpBB/styles/prosilver/template/posting_editor.html#L45

And in line 2 a indentation? https://github.com/phpbb/phpbb/blob/develop-ascraeus/phpBB/styles/prosilver/template/posting_editor.html#L2

And the indentation of the bottom seems incorrect, with missing </div>'s: https://github.com/phpbb/phpbb/blob/develop-ascraeus/phpBB/styles/prosilver/template/posting_editor.html#L186
