Input focus on iPhone

The first input here has css code like this:

#small {
  font-size: small;
}

On iOS devices, this causes the screen to zoom in on the input when it is focused.

This iPhone behavior has been prevented on this page by:

• using a media query to detect a narrow screens,
• changing the font size of the input if the screen is narrow,
• and using selector syntax that will target and override inline font-size styles on inputs.
