Code 3 overlaying modals onto existing website

We are looking for someone to create three overlaying modals onto an existing website, while adding some javascript and CSS effects. Specifically: 1) Code the following elements onto an existing webpage: [login to view URL] (this is how the existing page looks like: [login to view URL]). Please make sure the background black overlay is structured exactly how it is in the screenshot. 2) Code the following modal onto a blank webpage: [login to view URL] Also add functionality so that when the 'Continue' button is clicked, or any of the background black overlay is clicked, the modal and the background overlay will disappear: [login to view URL] 3) Same as #2, but add an arrow to the right of the modal box: [login to view URL] Thanks!
