进度条可用于显示用户在进程中的进度。
要创建默认进度条,请将 .progress
类添加到容器元素并添加 .progress-bar
为其子元素添加类。使用 CSS width
属性设置进度条的宽度:
<div class="progress">
<div class="progress-bar" style="width:70%"></div>
</div>

<h2>Basic Progress Bar</h2>
<p>To create a default progress bar, add a .progress class to a container element and add the progress-bar class to its child element. Use the CSS width property to set the width of the progress bar:</p>
<div class="progress">
<div class="progress-bar" style="width:70%"></div>
</div>
</div>
</body>
</html>
进度条的高度默认为 1rem
(通常为 16px
)。使用 CSS 高度
属性来改变它:
<div class="progress" style="height:20px">
<div class="progress-bar" style="width:40%;"></div>
</div>

<div class="progress-bar" style="width:70%">70%</div>
