使用我們的寬度和高度實用程序輕松制作寬或高(相對于其父項)的元素。

寬度和高度實用程序從$sizesSass地圖中生成_variables.scss。包括支持25%,50%,75%,和100%默認。根據(jù)需要在這里生成不同的實用程序,修改這些值。

<div class="w-25 p-3" style="background-color: #eee;">Width 25%</div><div class="w-50 p-3" style="background-color: #eee;">Width 50%</div><div class="w-75 p-3" style="background-color: #eee;">Width 75%</div><div class="w-100 p-3" style="background-color: #eee;">Width 100%</div>


<div style="height: 100px; background-color: rgba(255,0,0,0.1);">  <div class="h-25 d-inline-block" style="width: 120px; background-color: rgba(0,0,255,.1)">Height 25%</div>  <div class="h-50 d-inline-block" style="width: 120px; background-color: rgba(0,0,255,.1)">Height 50%</div>  <div class="h-75 d-inline-block" style="width: 120px; background-color: rgba(0,0,255,.1)">Height 75%</div>  <div class="h-100 d-inline-block" style="width: 120px; background-color: rgba(0,0,255,.1)">Height 100%</div></div>

您也可以根據(jù)需要使用max-width: 100%;和使用max-height: 100%;實用程序。

<img class="mw-100" src="..." alt="Max-width 100%">


<div style="height: 100px; background-color: rgba(255,0,0,0.1);">  <div class="mh-100" style="width: 100px; height: 200px; background-color: rgba(0,0,255,0.1);">Max-height 100%</div></div>
