如何使用 HTML 和 CSS 正确显示此营养标签答案

【问题标题】：How do I make this nutrition label display properly with HTML and CSS如何使用 HTML 和 CSS 正确显示此营养标签
【发布时间】：2019-10-31 12:48:48
【问题描述】：

我正在设计一个网站，该网站将在其上显示营养标签，其中包含动态填充的营养信息。我在网上找到了一些免费的营养标签代码：https://codepen.io/chriscoyier/pen/egHEK 但由于某种原因，我的标签不像示例中的那样出现。

这是我的标签的显示方式：https://i.imgur.com/IEJsCq6.jpg

这就是我希望我的标签显示的方式：https://i.imgur.com/KgMCbJ1.jpg

我遗漏了一些行，并且一些格式不正确。我相信它与 @import "compass/css3";不能正常工作。

有谁知道如何让我的标签显示得与 codepen 中的标签完全一样？谢谢。

<style>
@import "compass/css3";

【问题讨论】：

标签： html css import label

【解决方案1】：

您在 html 中嵌入了 scss 样式表，您不能直接将 SCSS (Sassy CSS) 文件插入到您的 HTML 中。这是因为 SASS 是 CSS3 语法的超集（或所谓的预处理器或扩展），Web 浏览器不支持。

转到您的 codepen (https://codepen.io/chriscoyier/pen/egHEK)，在 css 部分中，有一个下拉菜单提供将 scss 编译为 css 的选项（查看已编译的 css）。点击它，你会得到最终编译好的css如下：

@charset "UTF-8";
.image {
  width: 250px;
  float: left;
  margin: 20px;
}

body {
  font-size: small;
  line-height: 1.4;
}

p {
  margin: 0;
}

.performance-facts {
  border: 1px solid black;
  margin: 20px;
  float: left;
  width: 280px;
  padding: 0.5rem;
}
.performance-facts table {
  border-collapse: collapse;
}

.performance-facts__title {
  font-weight: bold;
  font-size: 2rem;
  margin: 0 0 0.25rem 0;
}

.performance-facts__header {
  border-bottom: 10px solid black;
  padding: 0 0 0.25rem 0;
  margin: 0 0 0.5rem 0;
}
.performance-facts__header p {
  margin: 0;
}

.performance-facts__table, .performance-facts__table--small, .performance-facts__table--grid {
  width: 100%;
}
.performance-facts__table thead tr th, .performance-facts__table--small thead tr th, .performance-facts__table--grid thead tr th,
.performance-facts__table thead tr td,
.performance-facts__table--small thead tr td,
.performance-facts__table--grid thead tr td {
  border: 0;
}
.performance-facts__table th, .performance-facts__table--small th, .performance-facts__table--grid th,
.performance-facts__table td,
.performance-facts__table--small td,
.performance-facts__table--grid td {
  font-weight: normal;
  text-align: left;
  padding: 0.25rem 0;
  border-top: 1px solid black;
  white-space: nowrap;
}
.performance-facts__table td:last-child, .performance-facts__table--small td:last-child, .performance-facts__table--grid td:last-child {
  text-align: right;
}
.performance-facts__table .blank-cell, .performance-facts__table--small .blank-cell, .performance-facts__table--grid .blank-cell {
  width: 1rem;
  border-top: 0;
}
.performance-facts__table .thick-row th, .performance-facts__table--small .thick-row th, .performance-facts__table--grid .thick-row th,
.performance-facts__table .thick-row td,
.performance-facts__table--small .thick-row td,
.performance-facts__table--grid .thick-row td {
  border-top-width: 5px;
}

.small-info {
  font-size: 0.7rem;
}

.performance-facts__table--small {
  border-bottom: 1px solid #999;
  margin: 0 0 0.5rem 0;
}
.performance-facts__table--small thead tr {
  border-bottom: 1px solid black;
}
.performance-facts__table--small td:last-child {
  text-align: left;
}
.performance-facts__table--small th,
.performance-facts__table--small td {
  border: 0;
  padding: 0;
}

.performance-facts__table--grid {
  margin: 0 0 0.5rem 0;
}
.performance-facts__table--grid td:last-child {
  text-align: left;
}
.performance-facts__table--grid td:last-child::before {
  content: "•";
  font-weight: bold;
  margin: 0 0.25rem 0 0;
}

.text-center {
  text-align: center;
}

.thick-end {
  border-bottom: 10px solid black;
}

.thin-end {
  border-bottom: 1px solid black;
}

将此css嵌入到您的html中，它应该可以工作。请把.performance-facts的宽度从280增加到300，这样会很好看。

啊，是的，现在知道了。太感谢了。真的很感激。
