Styles don't carry across on translated pages

Hi team – hoping you can help. On my site here

http://rfl.shortiedesigns.com/ – you’ll notice on some of my modules that are using a custom class – they dont’ show up on the translated pages

http://rfl.shortiedesigns.com/%E9%A1%B5%E7%A0%81/?lang=zh-hans

EG – under the blue section – there’s a yellow border and under the yellow section there’s an orange border – however on the translated pages – this doesn’t show up. I have these styles in my child theme’s stylesheet – can you please advise what I need to do?

Cheers
