Maintain fixed size on large screen
Normally, content scales up on larger screens, which is great for hero or presentation-type sections. However, sometimes a fixed content size on large screens is needed for long text sections, such as articles, to maintain readability. If you need to keep the size fixed, enable the "Lock Content Size" option in the Box Settings panel.
