61. Hierarchy of HTML Source Code (Selenium Java 2026)

Understanding the Hierarchy of HTML Source Code 🌐

In HTML, everything is structured like a tree. At the top, we have the html element, which contains two main branches: head and body.

* The head holds metadata like the title.
* The body contains the visible content of the page, such as paragraphs.

Each element has relationships:
• Parent → directly contains another element
• Child → directly inside a parent
• Grandparent / Grandchild → one level further up or down
• Siblings → elements sharing the same parent

Example:
Two paragraph elements inside the body are siblings.

This structure is essential for working with CSS selectors and XPath expressions, allowing precise targeting of elements in a webpage.

Mastering this hierarchy makes debugging and styling much easier.
