This code snippet is written in CSS and it defines rules for making certain elements visible when specific elements in a document are targeted via id or name attributes.

What the code does:

1. It operates within a container element with the id of workskin.
2. It leverages the :target pseudo-class in CSS, which is used to apply styles to an element that matches the document's current hash (from the URL fragment, e.g., #elementID).
3. The code ensures that when an element within or related to workskin is targeted, certain sibling elements (indicated as classes somniant1, somniant2, somnium, etc.) become visible with display: block.

Explanation of the selectors:

• #workskin #somniant1:target ~ .somniant1:

  • Checks if an element with id='somniant1' inside the workskin container is targeted (via the URL hash #somniant1).
  • If it is targeted, this selector will set a sibling element with the class somniant1 to display: block.

• #workskin :target[name='somniant1'] ~ .somniant1:

  • Checks if a targeted element (via the URL hash) has the attribute name='somniant1' inside the workskin container.
  • If it is targeted, this selector will make a sibling element with the class somniant1 visible by setting its display to block.

This process repeats for the other ids or name attributes: somniant2, somniant3, somnium, end, and cssoff.

Summary:

This code makes specific sibling elements (.somniant1, .somniant2, etc.) visible (display: block) when an element with a matching id or name in the workskin container is targeted (via the document's URL fragment). This could be used for showing hidden sections or toggling content dynamically without JavaScript, relying entirely on CSS targeting.
