-=== Changing the stack-limit of a container
-
-If you have a single container with a lot of windows inside it (say, more than
-10), the default layout of a stacking container can get a little unhandy.
-Depending on your screen’s size, you might end up with only half of the title
-lines being actually used, wasting a lot of screen space.
-
-Using the +stack-limit+ command, you can limit the number of rows or columns
-in a stacking container. i3 will create columns or rows (depending on what
-you limited) automatically as needed.
-
 *Syntax*:
------------------------------
-stack-limit cols|rows <value>
------------------------------
 
 *Examples*:
--------------------
-# I always want to have two window titles in one line
-stack-limit cols 2
-
-# Not more than 5 rows in this stacking container
-stack-limit rows 5
--------------------
