In the singularity demo, there are a few samples using a push and pull mixin. When used they adjust content placement across the gutter. Looking high and low, I could not find any documented reference to these mixins. Are they part of the long term feature set or a leftover? If not, what is the recommended way to do this sort of gutter shift?
Found the answer here
Push/Pull are currently non-documented features that are being deprecated in Singularity 1.2.0. They make sense when using float output method and symmetric grids, but don't make sense for any other combination we can think of. Instead, we recommend utilizing the isolation output style (or, if you're feeling adventurous, the new calc output style in Singularity Extras)
The other option is to write your own mixin with the use of the grid-span, column-span, and gutter-span functions.
Having read about the deprecation of push/pull in Ver 1.2.0, I have just swapped my pull spans for isolation spans. It was so easy, I can't imagine why I hadn't used that method before. A lot of Singularitygs has to be learnt by trial and error, but perhaps the next set of docs will be better. I have also seen that they are removing the grid-overlay and grid-toggle from Ver 1.2.0. That's a shame. I got them working beautifully despite the lack of documentation. Still, the background-grid works well.
