Forum registration page and few other pages are not responsive on mobile

[JohnRip3r]

Registration page is always like this form day one not complaining but it's is 



Thread are not responsive at all on mobile



This is a good example threads on mobile are not properly formatted. 
On my forums theme has it's own set of problems 
Like uid=289 profile looks different then uid=1 
Has same set of things on both profiles 
css code is effecting responsiveness of theme not sure how but it is.
