- JavaScript API
Usage
- Favor flexbox for layout over other layout techniques
- Flexbox classes use pure flex properties to afford layouts in any direction or alignment
- Be aware of flexbugs and especially test complex layouts for browser differences

alignment
- Our alignment classes are useful for aligning flex items
- Properties include
align-items
align-content
align-self
justify-content
- Values include alignment values that are supportable by our browser coverage
- W3C categorizes values as positional | baseline | distribution

border-width
Melding and welding refer to the union of borders between siblings. meld
and weld
do the same job but with opposing techniques. Compose them together to remove any inner borders. stack
affects vertical union. shelf
affects horizontal union.
.meld-stack
- meld stacked borders into one via:not(:first-child)
.meld-shelf
- meld shelved borders into one via:not(:first-child)
.weld-stack
- weld stacked borders into one via:not(:last-child)
.weld-shelf
- weld shelved borders into one via:not(:last-child)

float
We avoid floats where possible due to the abundance of more maintainable techniques such as flexbox for many scenarios. We provide .float-none
, .float-left
, .float-right
, .clearfix
for transitional use and special cases.
list-style
Use these on li
or its ul
or ol
to affect all children. These only apply when display
is list-item
. Avoid inside
when its children are block
because browsers vary in how inside blocks appear.
.list-disc
sets type todisc
(initial).list-circle
sets type tocircle
.list-outside
sets position tooutside
(initial).list-inside
sets position toinside
.list-none
sets style tonone

JavaScript API
We are developing a JavaScript API to help component developers reliably compose classes.
npm install @plangrid/structure
const structure = require("@plangrid/structure");
structure
is a frozen cader
instance.
structure.fuse("FontXL") // "family-os weight-semibold size-42px line-single"
structure.fuse("Tap") // "family-os preset-button fill-current pointer"
structure.fuse("Tap FontXL") // Unique fusion of both
structure.bond("FontXL another") // Unique bonding of saved atom(s) and unsaved atom(s)
structure.bond("FontXL m0 mb1") // "family-os weight-semibold size-42px line-single m0 mb1"
.bond
permits mixing atoms with external classes whereas.fuse
is strictly atoms that have been saved- Call
structure.help()
for help .clone
is available for feature work
const feature = structure.clone() // new instance contains saved structure atoms
feature.save({/* ... */}) // can save more atoms if unique from structure atoms
