The display of mobile shopping cart interface exceeds the screen range

Hello, when I use the ella-5.0.2-sections-ready template, there is a problem that the display on the mobile phone is abnormal. Specifically, open our store, click one of the goods, and click to add to the shopping cart. The displayed shopping cart screen exceeds the display boundary of the screen. You need to slide the screen to see the complete screen. Please help check the problem.

我手机试了下,可以正常显示,用的是Chrome浏览器
