PageTree Inspector is a free Chrome add-on that allows you to visualize the distribution of DOM element nodes within the document tree of any web page. With this tool, you can generate interactive tree views for any element, providing visual insight into its placement.

One of the key features of PageTree Inspector is the ability to visualize document trees. It allows you to see the organization of DOM nodes in any web page through interactive tree representations. This helps you understand the structure and hierarchy of the elements on the page.

Using the inspector tool, you can select any element on the page and generate a dedicated interactive tree view for that element. This gives you a detailed visual representation of its placement within the document tree. You can easily navigate through parent, child, and sibling nodes to grasp the relationships between elements.

PageTree Inspector also offers a Dark Mode option, allowing you to reduce eye strain during late-night sessions. This provides a more comfortable experience when analyzing the document tree.

Additionally, you can customize the orientation of the tree view, choosing between horizontal or vertical layouts. You can also choose from various path rendering styles, such as diagonal, straight, elbow, or step, to customize the look of the visualization.

With PageTree Inspector, you can keep up with document tree changes by refreshing the view and instantly viewing updates. It is a valuable tool for web developers and designers who want to gain a better understanding of the structure and organization of web pages.
