I am using the jquery modal.js file and when I click on the x the box doesn't close.
Is something wrong or covering the x.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

And how do we get the modal?
In .modal-body {} you are moving the content up above the close button with top:-20px
add this in your document.ready block or in a script tag at the end of your body tag

$(".modal button.close")
    .click(function() { 

Open in new window

.modal-header .close {}

in your contact-form.css
delete the top: -20px

.modal-body {
  position: relative;
  padding: 20px;
  /* top:-20px; */ <--- comment or delete this style
