在特定螢幕上以 Bootstrap 水平方式顯示 flex 專案
若要在不同螢幕尺寸中水平設定 flex 專案,請使用 flex-*-row 類。
可變螢幕尺寸已設定針對小、中、大及超大螢幕尺寸。讓我們看看如何為小螢幕尺寸水平對齊 flex 專案:-
<h2>Flex Row (Small Screen)</h2> <div class="d-sm-flex flex-sm-row bg-primary mb-3"> <div class="p-2 bg-primary">Audi</div> <div class="p-2 bg-warning">BMW</div> <div class="p-2 bg-secondary">Benz</div> </div>
以下是一個在不同螢幕尺寸中水平顯示 flex 專案的示例:-
