How do you get HTML code working on mobile version of website?

Check out what you can do on the web version at https://www.inspire.buzz/ . Basically you can type in text in the top area that says “Type your project name here” and it fills in the area and a few other areas on the website with the text you type in.

If you don’t create a mobile version of the website, then it works fine on the phone but everything is so small you can’t read it. So I created a mobile version, but the ability to type the text in goes away! I can’t even see the place holding text that says “type your project name here” on the mobile version.

I’m attaching a video of the mobile version and below is the code used to make the text thing work on the desktop version.
