The jqForm PHP class uses the jQuery UI CSS Framework to style look and feel, including colors and background textures. We recommend using the ThemeRoller tool to create and download custom themes that are easy to build and maintain.
If a deeper level of customization is needed, there are widget-specific classes referenced within the jquery.ui.autocomplete.css stylesheet that can be modified. These classes are highlighed in bold below.

Sample markup with jQuery UI CSS Framework classes

<form name="myform" method = "post" id = "myform" >
    <table style="">
       <thead>
          <tr>
             <th align='left' colspan="2">
                 <div class="ui-state-default ui-corner-all" style = "padding:6px;" >
                    <span class="ui-icon ui-icon-pencil" style="float:left; margin:-2px 5px 0 0;"></span>
                    Address Details
                 </div>
              </th>
           </tr>
         </thead>
         <tbody>
            <tr>
               <td style="padding-top: 3px"> 
                  <label for="myform_name">Name</label>
               </td>
               <td style="padding-top: 3px">
                  <input size = "40" id = "myform_name" name = "name" class = " ui-input ui-widget-content ui-corner-all" type = "text" />
               </td>
           </tr>
            ...
           <tr>
              <td colspan="2">
                  <div name='newGroup' style = "text-align:right;width:100%;" id = "myform_newGroup" name = "newGroup" >
                     <input value = "Submit" id = "newSubmit" class = "ui-button ui-widget ui-state-default ui-corner-all ui-button-text-icon-primary" type = "submit" />
                  </div>
              </td>
           </tr>
        </tbody>
     </table>
</form>
