[RESOLVED] Form error on iPhone

I hope this question belongs in this forum.

I created a basic website that uses php.

My login form loads just fine on most browsers, and will load/work properly on my Android phone. When the browser loads the page on an iPhone, once the user clicks on the username or password field, the onscreen keyboard shows and there is a cursor in the textbox. However, the iPhone freezes immediately and locks up. Nothing can be done except close the browser!

The form works just fine on my iPad and Android, as mentioned.

Here's the css and form I am using:

Code:

<style type="text/css">
        * {
                margin: 0px;
                padding: 0px;outline: none;
        }

        body {
                background: #666;
        }

        form {

Can anyone shed a little light on the issue? Thank you!
