Layout Issue in HTML form

Question

I am trying to make an html form that has various fields. I have created separate divs and using jquery to animate them. On the main page, when I click "manage users" button some elements gets displayed on page. What I am trying to achieve is to align these fields properly using a table element but when I use <table> tag the form elements gets displayed outside the div. How can I make it so when I click the "manage users" button the elements are properly displayed using table tag.

Here is my code :

    $(document).ready(function(){
    $("#flip").click(function(){
        $("#panel").slideToggle("fast");
        $( "#panel1" ).hide( "slow");
        $( "#panel3" ).hide( "slow");


    });


    $("#ff").click(function(){
        $("#panel1").slideToggle("fast");
        $( "#panel" ).hide( "slow");
        $( "#panel3" ).hide( "slow");

    });

    $("#man_users").click(function(){
        $("#panel3").slideToggle("fast");
        $( "#panel" ).hide( "slow");
        $( "#panel1" ).hide( "slow");

    });
    });    

  #ff,#flip,#man_users,#add_user{

    padding: 5px;
    //text-align: center;
    background-color: #D9ECF5;
    border: solid 1px #88949A;



    }
    #panel,#panel1,#panel3 {
    padding: 5px;
    //text-align: center;
    background-color: rgb(0,136,159);
    border: solid 1px #88949A;
    color:white;
}

#panel,#panel1,#panel3 {
    padding: 50px;
    display: none;
}

#ff:hover,#flip:hover ,#man_users:hover,#add_user:hover{ 
    background-color:#A0CFE6;

Answer 1

You complete HTML structure is incorrect. You have div outside TD, you have form closed after the its container... I tried to clean it up but not sure about the result...

You'd better try to validate your dom using w3c validator

$(document).ready(function(){
    $("#flip").click(function(){
        $("#panel").slideToggle("fast");
        $( "#panel1" ).hide( "slow");
        $( "#panel3" ).hide( "slow");


    });


    $("#ff").click(function(){
        $("#panel1").slideToggle("fast");
        $( "#panel" ).hide( "slow");
        $( "#panel3" ).hide( "slow");

    });

    $("#man_users").click(function(){
        $("#panel3").slideToggle("fast");
        $( "#panel" ).hide( "slow");
        $( "#panel1" ).hide( "slow");

    });
    });

#ff,#flip,#man_users,#add_user{

    padding: 5px;
    //text-align: center;
    background-color: #D9ECF5;
    border: solid 1px #88949A;



    }
    #panel,#panel1,#panel3 {
    padding: 5px;
    //text-align: center;
    background-color: rgb(0,136,159);
    border: solid 1px #88949A;
    color:white;
}

#panel,#panel1,#panel3 {
    padding: 50px;
    display: none;
}

#ff:hover,#flip:hover ,#man_users:hover,#add_user:hover{ 
    background-color:#A0CFE6;
