Reduced all max-width by 1 to fix bugs caused by overlapping cases (e.g. for 768px both min-width: 768px & max-width: 768px would be applied).
Fixed bug where sidebar is not shown on mobile site after closing content (due to usage of old function isMobile).
Fixed bug where scroll bar persisted position through different contents.
