Lovelace column_width broken since 0.81?

Hello everyone,

In my lovelace interface, I want to limit the number of entities/sensors which are displayed next to each other. So if I want, for example, two objects next to each other instead of 3/4/5, I am using the following code in lovelace:

column_width: calc(100% / 2)

Since 0.81 this doesn’t work anymore, once the new version of the frontend is loaded.

Does anyone know what goes wrong and how it can be solved?

Thank you.

Adam.

On the left: new situation. On the right: old situation.

I found the answer. Instead of this:
column_width: calc(100% / 2)
you now have to use:
columns: 2
