Answer №1

To ensure the correct functionality of the z-index, it is essential to include either position: relative or position: absolute; in your CSS styles. You can view a working example on this jsfiddle link

table {
    position: relative; 
    background-color: white;
    height: 300px;
    width: 300px;
}

Just include the following line of code within the click event:

$('table').css({ 'position': 'relative' });

$('button').click(function() {
    $('body').append("<div class='overlay'></div>");
    $('table').css('zIndex', '60');
    $('table').css({ 'position': 'relative' });
});

Answer №3

Include the position property in your table styles. It seems like you need to add position: relative;.

The z-index will not function correctly unless the element has a position property defined.

table {
    position: relative; /* necessary for z-index */
    background-color: white;
    height: 300px;
    width: 300px;
}

A different method is to establish a new class or multiple classes and utilize .addClass() or .toggleClass() to apply them.

.bgRed {background-color:red;}

$('button').click(function() {
   $('body').append("<div class='overlay'></div>");
   $('table').addClass('bgRed');
});
