Quasar提供了CSS类来帮助您为DOM元素或组件提供间距。 所有选项都以q-为前缀，然后细分为类型（T），方向（D）和大小（S）。 有关所有可能的排列，请参见下表。
语法
q-[p|m][t|r|b|l|a|x|y]-[none|auto|xs|sm|md|lg|xl]
T D S
T - type
- values: p (padding), m (margin)
D - direction
- values:
t (top), r (right), b (bottom), l (left),
a (all), x (both left & right), y (both top & bottom)
S - size
- values:
none,
auto (ONLY for specific margins: q-ml-*, q-mr-*, q-mx-*),
xs (extra small),
sm (small),
md (medium),
lg (large),
xl (extra large)
例子
<!-- 所有方向小的padding -->
<div class="q-pa-sm">...</div>
<!-- 项部中margin, 右边小margin -->
<q-card class="q-mt-md q-mr-sm">...</q-card>
Flex插件(Addons)
启用后（通过quasar.conf.js > framework > cssAddon: true），它将为所有与间距相关的CSS类提供断点感知版本。
请注意，启用后，CSS占用空间将明显增加。 因此，只有在您确实需要时才这样做。
.q-(p|m)(t|r|b|l|a|x|y)-<bp>-(none|auto|xs|sm|md|lg|xl)
例子: q-pa-xs-md q-pa-sm-sm q-px-md-lg q-py-md-md
