css

.footer {     position:absolute;     bottom:0px;     width:100%; }

jquery

$(".gameschedule .addevent").bind('click', function () {     $(".gameschedule tr:nth-child(2)").after('<tr><td><input type="text"</td><td><input type="text"</td><td><input type="text"</td><td><input type="text"<td><td><input type="text"</td></tr>'); });

html

<form name="gameform" class="gameschedule"><!--form games--> <table  >     <tr>         <td colspan="5">             <table>                 <tr>                     <td align="left">team name</td>                     <td><input type="text" /></td>                 </tr>             </table>         </td>     </tr>     <tr>         <td>date</td>         <td>time</td>         <td>opponent/event</td>         <td>h/a</td>         <td>location</td>     </tr>     <tr>         <td><input type="text"</td>         <td><input type="text"</td>         <td><input type="text"</td>         <td><input type="text"</td>         <td><input type="text"</td>     </tr>     <tr>         <td colspan="2"><input type="button" class="addevent" value="add event"/></td>     </tr> </table> </form>

one way put footer in div id of 'footer', use jquery.

$(window).bind("load", function () {      var footerheight = 0,        footertop = 0,        $footer = $("#footer");      var contentheight = 0,        contenttop = 0,        $content = $("#content");        positionfooter();      function positionfooter() {          footerheight = $footer.height();         footertop = ($(window).scrolltop() + $(window).height() - footerheight) + "px";          contentheight = $content.height();         contenttop = ($(window).scrolltop() + $(window).height() - contentheight) + "px";           if (($(document.body).height() + footerheight + contentheight) < $(window).height()) {             $footer.css({                 position: "absolute"             }).animate({                 top: footertop             }, 0)         } else {             $footer.css({                 position: "static"             })         }     }     $(window)            .scroll(positionfooter)            .resize(positionfooter) });
