Use the 'spacing' template. More examples

The most important change is to say "for the named breakpoint ( `sm`, `md`, `lg`, `xl`) and above".
The existing "hiding elements para" (not yet live) is exactly what's needed.
Keep simple for "english as a second language" people (e.g. hide not hidden)

-## Common `display` values
+## How it Works
 
-The [`display` property](https://developer.mozilla.org/en-US/docs/Web/CSS/display) accepts a handful of values and we support many of them with utility classes. We purposefully don't provide every value as a utility, so here's what we support:

-- `.d-inline`
-- `.d-inline-block`
-- `.d-block`
-- `.d-table`
-- `.d-table-cell`
-- `.d-flex`
-- `.d-inline-flex`
 
-Put them to use by applying any of the classes to an element of your choice. For example, here's how you could use the inline, block, or inline-block utilities (the same applies to the other classes).
+## Notation
+
+The classes are named using the format 
+* `d-{display}` - for all content
+* `d-{breakpoint}-{display}` - ** for the named breakpoint ( `sm`, `md`, `lg`, `xl`) and above.**
+
+Where *display* is one of:
+
+* `none`
+* `inline`
+* `inline-block`
+* `block`
+* `table`
+* `table-cell`
+* `flex`
+* `inline-flex`
+
+For example, `d-lg-none` sets `display:none` on screens larger than the lg breakpoint.
+
+Combine these classes to get the effect you need.
