Question:
How can I determine the maximum size of an INPUT field?
Answer:
Although you can certainly use JavaScript to find out the size of your user’s screen or the size of their browser window, this information doesn’t help much when you want to set the size of your form INPUT fields. This is because the browser and the user’s platform dictates how form elements are displayed and you have very limited control. In addition, on some platforms, like Windows 95/98/NT, users can customize the size and style of the fonts used by the system. This makes setting the size of your INPUT controls even harder. There isn’t much of a work-around for this issue. The only thing you can do is test, test, test.
