Bundle works wrong for css - html

Question

I have these css files included in layout
<!-- Dropdown Menu -->
<link rel="stylesheet" href="~/Content/superfish.css">
<!-- Date Picker -->
<link rel="stylesheet" href="~/Content/bootstrap-datepicker.min.css">
<!-- CS Select -->
<link rel="stylesheet" href="~/Content/cs-select.css">
<link rel="stylesheet" href="~/Content/cs-skin-border.css">
<!-- Themify Icons -->
<link rel="stylesheet" href="~/Content/themify-icons.css">
<!-- Flat Icon -->
<link rel="stylesheet" href="~/Content/flaticon.css">
<!-- Icomoon -->
<link rel="stylesheet" href="~/Content/icomoon.css">
<!-- Flexslider -->
<link rel="stylesheet" href="~/Content/flexslider.css">
<!-- Style -->
<link rel="stylesheet" href="~/Content/style.css">
now I want to move these files in bundle so I did that:
public static void RegisterBundler(BundleCollection bundles)
{
bundles.Add(new StyleBundle("~/Content/style.css").Include(
"~/Content/superfish.css",
"~/Content/bootstrap-datepicker.min.css",
"~/Content/cs-select.css",
"~/Content/cs-skin-border.css",
"~/Content/themify-icons.css",
"~/Content/flaticon.css",
"~/Content/icomoon.css",
"~/Content/flexslider.css",
"~/Content/style.css"
));
BundleTable.EnableOptimizations = true;
}
and in my layout:
#Styles.Render("~/Content/style.css")
but from this:
it goes to this:
some of css code is missing when i open this new css file (from browser developer tool). Especially whole first file is missing (superfish.css) but it is in the same folder as others
What did I wrong?

Answer 1

It might get confused and renders the actual style.css instead of the bundle. Try changing the name of the bundle to something else, i.e. new StyleBundle("~/Content/main.css"). Also, you probably using the render wrong - it should be #Styles.Render("~/Content/style") (note the removed .css part)

Answer 2

Bundling is a new feature in ASP.NET 4.5 that makes it easy to combine or bundle multiple files into a single file.
The Bundle class Include method takes an array of strings, where each string is a virtual path to resource.
Change your code like below:
Note : remove the file extension inside the StyleBundle()
public static void RegisterBundler(BundleCollection bundles)
{
//
bundles.Add(new StyleBundle("~/Content/style").Include(
"~/Content/superfish.css",
"~/Content/bootstrap-datepicker.min.css",
"~/Content/cs-select.css",
"~/Content/cs-skin-border.css",
"~/Content/themify-icons.css",
"~/Content/flaticon.css",
"~/Content/icomoon.css",
"~/Content/flexslider.css",
"~/Content/style.css"
));
BundleTable.EnableOptimizations = true;
}
In Layout: Call like below
#Styles.Render("~/Content/style")
