CSS help on Mobile site / smaller screen resolutions

Hi, Had the mobile site looking perfect then one of the recent changes must have messed up everything, seems to have lost lots of custom changes + new issues came up.
Previous issue was the text was appearing really small now its resolved but need help with these CSS changes (mostly colour and layouts):
