Foundation 进度条可以作为程序处理的程度来显示：
我们可以在 <div> 元素中使用 .progress 类来创建进度条，
.meter 类用于子元素(<span>)。我们可以在 <span> 元素中设置进度百分比，如下所示：
实例
<div class="progress">
<span class="meter" style="width:70%"></span>
</div>
<span class="meter" style="width:70%"></span>
</div>
进度条颜色
默认情况下，进度条颜色为蓝色。不同颜色的类为：.secondary, .success, 或
.alert:
实例
<div class="progress">
<span class="meter" style="width:50%"></span>
</div>
<div class="progress secondary">
<span class="meter" style="width:50%"></span>
</div>
<div class="progress success">
<span class="meter" style="width:50%"></span>
</div>
<div class="progress alert">
<span class="meter" style="width:50%"></span>
</div>
<span class="meter" style="width:50%"></span>
</div>
<div class="progress secondary">
<span class="meter" style="width:50%"></span>
</div>
<div class="progress success">
<span class="meter" style="width:50%"></span>
</div>
<div class="progress alert">
<span class="meter" style="width:50%"></span>
</div>
圆角进度条
.radius 和 .round 类用于为进度条添加圆角效果：
实例
<div class="progress">
<span class="meter" style="width:50%"></span>
</div>
<div class="progress radius">
<span class="meter" style="width:50%"></span>
</div>
<div class="progress round">
<span class="meter" style="width:50%"></span>
</div>
<span class="meter" style="width:50%"></span>
</div>
<div class="progress radius">
<span class="meter" style="width:50%"></span>
</div>
<div class="progress round">
<span class="meter" style="width:50%"></span>
</div>
进度条尺寸
可以使用 .small-num 或 .large-num 来修改进度条的宽度，
num 是一个数字在 1(8.33%) 和 12(default (100%)) 之间:
实例
<div class="progress large-1">
<span class="meter" style="width:50%"></span>
</div>
<div class="progress large-6">
<span class="meter" style="width:50%"></span>
</div>
<div class="progress large-9">
<span class="meter" style="width:50%"></span>
</div>
<div class="progress large-11">
<span class="meter" style="width:50%"></span>
</div>
<!-- Default width -->
<div class="progress large-12">
<span class="meter" style="width:50%"></span>
</div>
<span class="meter" style="width:50%"></span>
</div>
<div class="progress large-6">
<span class="meter" style="width:50%"></span>
</div>
<div class="progress large-9">
<span class="meter" style="width:50%"></span>
</div>
<div class="progress large-11">
<span class="meter" style="width:50%"></span>
</div>
<!-- Default width -->
<div class="progress large-12">
<span class="meter" style="width:50%"></span>
</div>
进度条标签
可以使用 CSS 为进度条添加标签。以下实例中我们添加了<span> 元素来显示百分比：
实例
<style>
.percentage {
position: absolute;
top: 50%;
left: 50%;
color: white;
transform: translate(-50%, -50%);
font-size: 12px;
}
</style>
<div class="progress">
<span class="meter" style="position:relative;width:75%">
<span class="percentage">75%</span>
</span>
</div>
<div class="progress success">
<span class="meter" style="position:relative;width:50%">
<span class="percentage">50%</span>
</span>
</div>
<div class="progress alert">
<span class="meter" style="position:relative;width:25%">
<span class="percentage">25%</span>
</span>
</div>
.percentage {
position: absolute;
top: 50%;
left: 50%;
color: white;
transform: translate(-50%, -50%);
font-size: 12px;
}
</style>
<div class="progress">
<span class="meter" style="position:relative;width:75%">
<span class="percentage">75%</span>
</span>
</div>
<div class="progress success">
<span class="meter" style="position:relative;width:50%">
<span class="percentage">50%</span>
</span>
</div>
<div class="progress alert">
<span class="meter" style="position:relative;width:25%">
<span class="percentage">25%</span>
</span>
</div>
