This is a reliable selector for a dynamic page: "webctrl idx='144' tag='IMG'/" True or False?

The selector "webctrl idx='144' tag='IMG'" is considered unreliable for dynamic pages because it uses an index-based approach to identify the element. In dynamic web applications, the structure and order of elements can frequently change, which means that relying on an index can lead to selecting the wrong element or failing to locate the element entirely if the page content is updated.

Dynamic pages often modify their content based on user interactions, data loading, or other triggers. When these changes occur, the element associated with a specific index can shift, meaning that index '144' may not always correspond to the same image or even the same type of element in future sessions or page loads. This inconsistency undermines the reliability of the selector.

Selectors that rely on more stable and unique attributes, such as class names, IDs that are static, or other identifiable attributes, tend to be more effective for targeting elements on dynamic pages. The reliance on index positioning is why the answer indicating the selector's unreliability is appropriate.
