<meta name="assert" content="An HTML 4 text input control must be focused in order to enter text into it. The :focus pseudo-class applies to a text input control while it has the focus (accepts keyboard events or other forms of text input).">
<style type="text/css">
span

color: white;
}
input:focus + span

color: green;

<p>Enter in the text field below with the pointing device or with the keyboard (with the tab key or with the "T" accesskey) and then enter some text into it. A message in green should then have appeared on its right-hand side indicating that such text field has received focus. In order to pass this test, the tester should not have to move the pointing device outside the text field.</p>
<div>
<input type="text" accesskey="T" tabindex="1"> <span>Focus received by text field</span>
