A few new features have landed in Susy 1.0.7, even as we work on more integrated syntaxes for 2.0.
Sub-pixel rounding has always been a problem for fluid design. Susy takes care of the most egregious layout-breaking cases, but there is no way to entirely eliminate the problem.
John Albin Wilkins has a demo of the problem, as well as a proposed solution. He hasn’t eliminated rounding errors, he just found a way to keep them from piling up. Every float is positioned relative to its container, rather than the float before it. It’s a bit of a hack, and removes content from the flow, so I don’t recommned building your entire layout on isolated floats, but it can be very useful as a spot-check when rounding errors are really causing you a headache.
(Note that rounding errors can still stack up when you use a gradient background for testing. Gradient background grids are useful, but you should never trust them as a pixel-exact guide.)
Using John’s method,
you can now isolate any grid element in susy,
with the simple
When you put several of those together, you can see how they have been removed from the flow:
The items can overlap, and stack in any order – almost as though they are positioned absolutely.
Isolation is most useful when
you are repeating the same grid math again and again,
such as image-galleries.
To help with that use-case,
we’ve added the
You just tell us how wide each item should be,
and we’ll calculate the locations,
applying them with nth-child selectors.
Change the span-width, and we’ll update everything for you:
Bleed has nothing to do with isolation, it just happened to appear in the same update. Bleed uses negative margins and equal-but-positive padding to let an element’s background “bleed” outside the area it would normally occupy.
Here’s an element bleeding 1-column outside our 6-column page layout:
You’ll notice that the context syntax is a bit different here:
(1 of 9) instead of
That’s the direction we’re heading with Susy 2.0,
and it’s very helpful in this case,
because there’s another argument we want to access easily.
Use the second argument to list which sides should do the bleeding
(defaults to “left right”).
You can also pass arbitrary widths in the first argument:
This can be especially useful to bleed across
bleed($grid-padding) and you’re there.
