You have not shared the error that you are encountering but I have a pretty good idea it has something to do with this:
@model IEnumerable<CMSFC.Models.ContentHtml>
you can not iterate an object, only a collection of object. So the above line should be:
@model IEnumerable<CMSFC.Models>
UPDATE: You have a Syntax error in your razor code. The error is indicating that the parser sees missing syntax - you should see a red squiggly line on this line of code:
@Html.DisplayFor(modelItem => item.Id)
Even though you are in an HTML page, the razor language still has the same syntax rules as C#. So from the above line, it is pretty easy to see that this line of code is not terminated with a '
;'. So it should be:
@Html.DisplayFor(modelItem => item.Id);
