Belly Button is a Chrome add-on developed by Alexander Grattan that aims to assist developers and accessibility engineers in inspecting buttons and ensuring they adhere to HTML standards and Web Content Accessibility Guidelines (WCAG). With its comprehensive set of features, Belly Button is a valuable tool for anyone involved in button development and accessibility optimization.

The main highlight of Belly Button is its interactive button and link inspector. This feature allows users to easily examine the structure and attributes of buttons and links on webpages. By inspecting these elements, developers can ensure that their buttons are properly implemented and accessible to all users.

In addition to the inspection capabilities, Belly Button also provides a helpful guide on button best practices and the HTML attributes that should be implemented. This guide serves as a valuable resource for developers, offering insights on how to create buttons that are not only visually appealing but also meet accessibility standards.

One notable feature of Belly Button is its ability to automatically add aria-labels (accessibility labels) to social media links and buttons. This automation saves time and effort for developers, ensuring that these important elements are properly labeled for accessibility purposes.

Belly Button is a free tool available on the Chrome platform. It falls under the category of Browsers and specifically belongs to the Add-ons & Tools subcategory. With its comprehensive inspection capabilities, button best practices guide, and automatic accessibility label addition, Belly Button is an invaluable asset for developers and accessibility engineers.
