Introduction to Nesting in CSS in Visual Studio 2022

In the world of web development, one of the very interesting and attractive features that has been added to CSS in recent years is the capability of Nesting, or in other words, writing styles within styles. This feature might seem a bit daunting to someone who is new, but believe me, it can significantly reduce the complexity of working with CSS.

There was a time when for every small change, a whole line of CSS code had to be written, and this issue caused style files to become bulky and unwieldy. With the introduction of the Nesting feature in the CSS world, styles can be written in a way that resembles the syntax used in languages like Sass and Less.

One thing that might surprise you is that you can now use this feature directly in Visual Studio 2022. Visual Studio 2022 has added the capability of Nesting from CSS as part of a more user-friendly and easier way to work with CSS files.

In the following, we will see a simple example of CSS Nesting to understand how to benefit from this capability:

.container {
  color: black;
  <header> {
       background-color: blue;
       h1 {
          font-size: 24px;
       }
  }
}

This was a simple example. In this example, you can see how elements can be nested within each other and how it makes the code cleaner. Now we will move on to explaining the above code:

.container:
This class is regarded as the main container that holds the initial styles like a primary color.

<header>:
This is included within the .container class and has its own specific styles like background color.

h1:
This element is another nested part defined within the header section, and it only specifies a specific aspect of the style for font size.
