Min Height

A floor for the column's height — it can grow taller, but never shorter.

Where to find it
Labelled Min Height in the "Selected Column" section of the Modify drawer.
Per device
Yes — you can set one value for every screen, or separate values for phone, tablet, and desktop.
Underlying CSS
minHeight

In plain English

Min Height gives a box a guaranteed depth while still letting it grow. Set 300px and a short piece of text still occupies a 300px-tall block; add ten paragraphs and the block simply gets taller to fit them.

That is almost always what you want instead of Height. A fixed height traps content and forces you to deal with overflow; a minimum height gives you the shape you designed without the risk.

When you would use it

  • Cards in a row should all look the same depth even though their text differs in length.
  • A hero section should be at least one screen tall but grow if the headline wraps: use 100vh here rather than in Height.
  • A coloured band needs presence on the page even when it holds very little.

How to change it

  1. Select the column, open "Selected Column", then "Min Height".
  2. Enter a number and choose a unit. Use vh when you want the value measured against the visitor's screen height.
  3. Add extra content temporarily to confirm the box grows the way you expect.
One value, or one per device? Every input in this setting sits under a “Same value for all resolutions” checkbox. Leave it checked for a single value everywhere, or uncheck it to give phones, tablets, and desktops their own. How per-device values work.

Watch out for

  • Min Height wins over Height. Setting both, with the minimum larger, means the height is ignored.
  • A min height in percent needs the surrounding element to have a height, which inside a normal row it usually does not. Use vh instead.
