What is the use of column layout in CSS?

Column layout is used to manage your webpage on the different screens size because people not like horizontal scroll and to make your webpage responsive you have to use column layout

Column layout is just like Newspaper. It makes easier to read the contents on the column layout because instead of line to line and full page reading, it provided block structure in which you can read easily.

The CSS multi-column layout extends the block layout mode to allow the easy definition of multiple columns of text. People have trouble reading text if lines are too long; if it takes too long for the eyes to move from the end of the one line to the beginning of the next, they lose track of which line they were on. Therefore, to make maximum use of a large screen, authors should have limited-width columns of text placed side by side, just as newspapers do.
