As you know, after adding the first element inside the container, the default height of the container is set based on the element. According to the screenshot below.
But in templates, such as header and footer, this does not happen and after adding the element, the container still maintains its default height. After reloading Builder, the problem is solved.
We’ve fixed this issue in Bricks 1.10, now available as a one-click update in your WordPress Dashboard.
