If you specify 3 borders, these borders will be displayed in IE9. As soon as you specify the 4th border, IE9 refuses to display any of the borders
Works:
.hello-button {
border-top: 2px solid #eee;
border-right: 2px solid #a9a9a9;
border-bottom: 2px solid #a9a9a9;
}
Does not work:
.hello-button {
border-top: 2px solid #eee;
border-right: 2px solid #a9a9a9;
border-bottom: 2px solid #a9a9a9;
border-left: 2px solid #eee;
}
