Magento checkout issue on mobile

$30 - $250

Project Description:
I'm having some problems with the checkout page on my Magento site, but only with mobile checkout. My site is responsive so the mobile version is using the same theme files as the desktop version. The problem is that when they go to checkout, they should be prompted to enter their Billing info in the standard Magento onepage checkout. The problem is that on mobile (I've checked on both iPhone and iPad) all the onepage steps are collapsed and you can't expand them. The user never has the option to enter in any of their info and will just have to abandon their shopping cart since they can't complete the sale. I've attached a screenshot from an iPhone and an iPad so you can see what it looks like to the user. I know it's something simple so I think it should be pretty easy to fix.

Skills required:
iPad, iPhone, Magento, MySQL, PHP
