Styles.Render in MVC4

Question

In a .NET MVC4 project how does @Styles.Render works?

I mean, in @Styles.Render(\"~/Content/css\") which file is it calling?

Polo I wouldn't use Bundles in MVC for multiple reasons. It doesn't work in your case because you have to set up a custom BundleConfig class in your Apps_Start folder. This makes no sense when you can simple add a style in the head of your html like so:

You can also add these to a Layout.cshtml or partial class that's called from all your views and dropped into each page. If your styles change, you can easily change the name and path without having to recompile.

Adding hard-coded links to CSS in a class breaks with the whole purpose of separation of the UI and design from the application model, as well. You also don't want hard coded style sheet paths managed in c# because you can no longer build "skins" or separate style models for say different devices, themes, etc. like so:

Using this system and Razor you can now switch out the Skin Path from a database or user setting and change the whole design of your website by just changing the path dynamically.

The whole purpose of CSS 15 years ago was to develop both user-controlled and application-controlled style sheet "skins" for sites so you could switch out the UI look and feel separate from the application and repurpose the content independent of the data structure.....for example a printable version, mobile, audio version, raw xml, etc.

By moving back now to this "old-fashioned", hard-coded path system using C# classes, rigid styles like Bootstrap, and merging the themes of sites with application code, we have gone backwards again to how websites were built in 1998.
