Why bundling CSS in ASP.NET Core is changed?

Question

I am trying to achieve bundling css in ASP.NET Core.

I have installed the following extension:

https://marketplace.visualstudio.com/items?itemName=Failwyn.BundlerMinifier64

I followed this article:

https://blog.elmah.io/how-we-do-bundling-and-minification-in-asp-net-core/

I have ended up with a bundleconfig.json file:

[
  {
    "outputFileName": "BundlA",
    "inputFiles": [
      "Content/animation.css",
      "Content/custome.css"
    ]
  }
]

A file name BundlA was generated under my solution.

It has some css related to the first part of my bundle only the animation.css.

Now in my view I have added

 <bundle name="BundlA" />

Did this supposed to result in having two links file, one for animation, one for custom.

Am I right or am I missing the concept ?

After starting the project, I checked the view source of the page - no css is included...

I have moved my content folder under wwwroot and changed the path also nothing happened

Any reason?
