Quickly toggle a Bootstrap Grid Overlay that automatically uses your application's styles to determine how it looks.
Click the Bootstrap Grid Overlay icon to toggle the overlay on and off. If Bootstrap Grid Overlay finds the Bootstrap grid classes in any of your application's CSS files, a Bootstrap grid will be displayed based on those styles.
Features:
- Allows user to click through the overlay to target specific elements while using the Chrome Developer Tools
- Allows user to enable/disable a fluid container
- Allows user to view the current Bootstrap breakpoint
- Allows user to set the opacity of the Bootstrap grid overlay
- Allows user to take screenshots with a Bootstrap grid overlay, which can be download, publish (via prntscr.com) and share to Twitter or Facebook (auto post)

- Awesome extension, just what I was looking for as a WP dev! Just one suggestion: Could you add the new Bootstrap xxl col (≥1400px)? Would make it 100% perfect and up to date!

- Hi there, I am a UX student and I am trying to use this extension to check the grids on various websites, does it function that way? Every page I pull up appears to show only 1 grid, indicated by the number "1" at the top of the screen. Can that be right...? Or am I not using this tool correctly? Thank you!

- Please support the scrollbar on the right side. A Scrollbar has a width of 17px. Please implement a checkbox to toggle this and use it for your calculation or for customized scrollbars, implement a option to enter a value for the scrollbar width.
