Reply To: Expanded Column Background comes late

[hiegl]

If this background is set to the row, the columns inside will not break anything, when moving responsively. I just tried.

Ah, your example has column backgrounds. I do not use column backgrounds, just the row background shining through.
But you are right, this method does not guarantee, that column content is always placed nicely relative to the background of it’s parent row’s BG.

Anyway, checking breakpoints is always good advice, as many “responsive” websites forgot about this.
