I'm working on making a page more responsive. To that end, I'm trying to make sure a web page looks and functions as intended on mobile devices. 

On the desktop, it works as expected. 

On the iPhone, it looks as expected, but doesn't work as expected. If you select the input field, it'll focus and bring up the keyboard. It however won't let you type anything. If you select the text input field once again, it'll finally allow you to type. 

Here's the link: [ASLChoice](http://www.aslchoice.com)

Make sure you view it using an iOS device to reproduce the issue. Any ideas? I've googled this issue, and it seems no results are showing on Google that are similar to my issue. I've also searched StackOverflow. 

Feedback is certainly appreciated. Thanks in advance!
