Aligning Text Across All Breakpoints
When you set the alignment for the content within a text Bric using the sidebar inspector alignment controls, the default behaviour is to apply the selected alignment setting to the current breakpoint and all breakpoints above (if the above ones, do not have an alternative alignment setting).
To quickly set the alignment of the content within a text Bric across all breakpoints (above and below), simply hold the option | alt key and then Left Click the alignment option in the sidebar inspector. Doing this will clear all current alignment settings, across all breakpoints and set them to the selected alignment option.
