使用四個預(yù)設(shè)的值與類別，即時的調(diào)整overflow屬性。預(yù)設(shè)情況下這些類別并非響應(yīng)式的。
This is an example of using
.overflow-auto on an element with set width and height dimensions. By
design, this content will vertically scroll.
This is an example of using
.overflow-hidden on an element with set width and height dimensions.
This is an example of using
.overflow-visible on an element with set width and height dimensions.
This is an example of using
.overflow-scroll on an element with set width and height dimensions.
<div class="overflow-auto">...</div>
<div class="overflow-hidden">...</div>
<div class="overflow-visible">...</div>
<div class="overflow-scroll">...</div>
使用Sass變量，你可以透過更改_variables.scss中的$overflows變量以自定義溢出通用類別。
