Changes between Initial Version and Version 1 of Ticket #41164, comment 2

initial	v1
2	2	* Removed globals from `column_screenshot` documentation. (Also changed `@since` value)
3	3	* Removed fixed width since it looked really bad in some cases and add some basic responsiveness to `<img />`. I am not sure how the screenshot should be presented but it looks as a good starting point.
	4	* Added `alt` and `title` attributes on `<img />`
4	5	* Fixed some spacings in code.
