Layout Debugger is a free Chrome extension developed by cdsnwoen that aims to assist web developers in debugging layout issues. This handy tool helps identify and highlight DOM elements that may be causing layout problems, making it easier to diagnose and fix issues related to element alignment, overflowing objects, and distinguishing between block and inline elements.

With Layout Debugger, each visible DOM element is outlined with a distinct color, providing a visual representation of the element's display property. Block elements are highlighted in blue, while inline elements are highlighted in purple. This clear distinction allows developers to quickly identify and differentiate between block and inline elements, aiding in the troubleshooting process.

One of the standout features of Layout Debugger is its ability to visually indicate when an element is overflowing the viewport. When an element is exceeding the boundaries of the viewport, it is outlined in red, providing an immediate visual prompt for overflowing divs or other elements. This feature can be particularly helpful in identifying and resolving layout issues related to overflowing content.

Overall, Layout Debugger is a valuable Chrome extension for web developers who need assistance in debugging layout issues. With its ability to highlight DOM elements, distinguish between block and inline elements, and visually indicate overflowing objects, it provides a practical and efficient solution for improving the layout of web pages.
