I am trying to make a small web utility that allows a user to enter some data. It has an external stylesheet. The stylesheet loads correctly in Firefox and Chrome but does not load in IE 11. I have run both the CSS and HTML through the W3C validator and everything appears to be fine. I looked at all the posts similar to this problem but still having the problem. Any suggestions will be greatly appreciated. Below is the HTML and CSS. I am not at web designer so my HTML and CSS is a bit rusty :). Also I removed the javascript since that functionality works. Its just appears the CSS will not load in IE 11.
#colA {
 width: 50%;
 float: left;
 max-width: 480px;
}
.userInputs {
 width: 90%;
 float: left;
}
#right {
 padding-top: 20px;
 float: left;
}
#userDisplay {
 width: 90%;
 float: left;
}
/* Styling for the Name/Value Pair List */
#listDisplay {
 min-width: 90%;
 float: left;
 height: 200px;
}
/* Styling for all  buttons */
.buttons {
 margin-bottom: 20px;
