/* Yes, there's actually a good reason for this...
|
* If the configured buttonText is set to something longer than the default,
|
* then it will quickly exceed the width of the hidden file input's "Browse..."
|
* button, so part of the custom button's clickable area will be covered by
|
* the hidden file input's text box instead. This results in a text-selection
|
* mouse cursor over that part of the button, at least in Firefox, which is
|
* confusing to a user. Giving the hidden file input a huge font-size makes
|
* the native button part very large so it will cover the whole clickable area.
