我正在设计一个网站,该网站将在其上显示带有动态填充的营养信息的营养标签。我在网上找到了一些营养标签的免费代码:https://codepen.io/chriscoyier/pen/egHEK但出于某种原因,我的标签不像示例中的那样出现。

我的标签是这样显示的:https://i.imgur.com/IEJsCq6.jpg

这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,一些格式不正确。我相信它与@import“compass/css3”有关;无法正常工作。

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";

最佳答案

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),网络浏览器不支持它。

转到你的 codepen ( https://codepen.io/chriscoyier/pen/egHEK ),在 css 部分,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)。单击它,您将获得最终编译的 css,如下所示:

@charset "UTF-8";
.image {

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 {

}
.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 {

}
.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。请将 .performance-facts 的宽度从 280 增加到 300,这样看起来会不错。
