[SOLVED] pre-written text in search field

[h4r00n]

Hey, I have my code below for the search form. Do you know how I can have pre-written text in the search field stating 'e.g. Social Work in Manchester' which disappears when the user clicks the search field?

 

   <form action='search.php' method='GET'>
      
      <center>
            <p><font size="5" style="font-family: Georgia, 'Times New Roman', Times, serif; font-size: 30px; color: #FF7113;">Quick Search</font></p>
        <p><font size="5" face="sans-serif">
          <input style='text' size ='50' name='search'>
          <input type='submit' name='submit' value='Search'
      >
          <br>
        </font></p>
      </center>
      
</form>
