Mobile view width and sub forum adjustment

[tyip]

How can I reduce the forum width?

I am using the mobile view that come with vbulletin (not the native app, but the web view). I am putting the forum within a frame in my game, so the forum must be slightly narrower than it is by default. Anyone know how?

Second, does anyone know how to make all sub forums display by default? On the mobile view, I need to tap on "sub forums" to show them each time I refresh the page.

I want to display:

Valor General
-General Discussion (a subforum)
-Pictures (subforum)
-World discussion (subform)

Social
-Off topic
-Music and entertainment

without making the users have to expand all subforums each time.
