-ms-grid-column not working in intellisense

I am trying to create a grid to use in IE 11 using VS and coding the CSS in VS 2017. I get the message 199px not a valid value for CSS3. Also the intellisense gives me -ms-grid-colum and not -ms-grid-columns. Can anyone help me out as to why VS is doing this. The code is:

.grid {
display: -ms-grid;
-ms-grid-cloumn: 100px 100px;
}

Thanks
