Execute the following code snippets either in the browser’s built-in JavaScript console or as a JavaScript bookmarklet.
Some are currently written as functions to be pasted into the console while others are intended to be JavaScript bookmarklets.
- Visualize screen reader user experience – strips presentational CSS, applies minimalist styling, and displays text alternatives rather than graphical content
- Detect if a webpage contains Shadow DOM content
- Generate a 5 second window before pausing script execution and opening the debugger
- Add keyboard operability to an element
- Adds a roving tabindex to a group of elements
When using a function in the built-in JavaScript console, be sure to first initialize the function in the console, then execute the function.
