How do I make my top banner image respond to mobile portrait view?

My form is working great.  However, in mobile phone portrait view the banner extends beyond the border.  I applied the mobile widget and unsuccessfully injected the CSS code for sizing.  Looking to Jot Team for assistance.

Thanks,

I see that you are having issues getting your jotform to display your logo properly.

When I inspected this problem I found a couple of issues so I have modified them via a separate test version of your form to help aid you with a potential solution to your problem.

Please check this modified demo of your form: http://form.jotform.us/form/51324545703147? 

Feel free to clone the above demo form back into your account if you are happy with it.

Here's how it looks in a screenshot on my iPhone (fixed):

Additionally, in case you are wondering how I fixed it basically what I did was moved your Logo from the Text Field which was html into our Image Field.

I then set the width of your logo in the Image Field to 600px and changed the alignment to Left.

I also removed the mobile responsive widget since your form responsiveness is already enabled and you can only use one or the other and not both. 

I hope this helps but if you need more help with any of this just let us know.
