I recall encountering this code before but I can't remember where:
<div.main>
// ....
</div.main>
<div.secondary>
// ....
</div.secondary>
Could someone please clarify for me what this syntax is referred to as and what its general purpose is?
For those familiar with certain editors and plugins such as emmet () or zen coding (https://code.google.com/archive/p/zen-coding/), you may have come across a quicker way to code HTML. These tools significantly speed up the coding process.
It appears that the usage you mentioned is not common in HTML code but can be utilized in CSS by using the element.class combination without the symbols <, &, and >. However, in HTML5, you have the option to use <main> for defining the main content of a webpage.

Meaning and Purpose
The
<main>tag specifies the primary content of a document.The content within the
<main>element should be distinct to the document, avoiding any repetitive elements found across various documents like sidebars, navigation links, copyright information, logos, and search forms.Note: A document should contain only one
<main>element, and it must NOT be nested within an<article>,<aside>,<footer>,<header>, or<nav>element.
I trust this explanation clears things up. The use of custom interfaces with unique tags might also exist, although I personally implement {{tag}} for dynamic templates rather than what you described.
