Modal will not open from href link - html

Question

I have followed a detailed instruction from https://www.webdesignerdepot.com/2012/10/creating-a-modal-window-with-html5-and-css3/ on creating a modal.
I have done everything to plan but when I go to click the modal in the navBar arrow link, it opens stating that #openModal cannot be found.
Attached is my HTML and CSS code:
body { /* General Body Properties */
font-family: Trebuchet MS, Georgia, Helvetica, sans-serif;
margin: 0;
overflow: hidden;
}
* { /* Key element to aligning <divs> (DO NOT REMOVE) */
box-sizing: border-box;
}
#wrapper {
bottom: 0;
left: 0;
overflow: hidden;
position: absolute;
right: 0;
top: 0
}
.header { /* Header properties featuring myEd and school emblems */
padding: 30px;
text-align: center; /* Aligns links in the navBar */
background-image: url(/Default/Img/backgroundHeader-4K.jpg);
background-size: cover;

}
.myEd-reverse {

}
.navBar a { /* Style the navBar links */
float: left;
display: block;
