html - 如何在不覆盖我的自定义 css 的情况下将 Glyphicons 添加到我的 Flask 应用程序？

问题描述

我正在尝试将一些Glyphicons插入到我的 Flask Web 应用程序中。

我将此行添加到<head>我的模板中：

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.0/css/bootstrap.min.css">

这是<head>我的layout.html文件，它被我的 Web 应用程序中的所有视图扩展：

<!DOCTYPE html>
<html lang="en" dir="ltr">
<head>
    <!-- Required meta tags -->
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

    <!-- Bootstrap CSS -->
    <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css"
          integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">

    <!-- My CSS file -->
    <link rel="stylesheet" type="text/css" href="{{ url_for('static', filename='main.css') }}">
    <!-- Glyphicons -->
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/css/bootstrap.min.css">


    <!-- Text in the tab bar -->
    <title>{{ title }}</title>

    <!-- Math formulas -->
    <SCRIPT SRC='https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML'></SCRIPT>
    <SCRIPT>MathJax.Hub.Config({tex2jax: {inlineMath: [['$', '$'], ['\\(', '\\)']]}})</SCRIPT>

</head>

例如，我在 html 文件中使用这一行：

<a href="#"><span class="glyphicon glyphicon-question-sign"></span></a>

它有效，但显然它覆盖了我在文件夹css中的static文件，因为我网站中所有视图的间距和组织都发生了变化。如何只添加我想要的字形而不覆盖我的css文件？

解决方案

如果您可以在服务器上托管bootstrap而不是使用 CDN

  1. 您可以下载自定义版本的 Bootstrap，并且只包含 Glyphicon 到 bootstrap
  2. 更好的是，只需将 glyphicon 特定样式复制到您的 CSS 文件中，它应该可以工作，例如：

@font-face {
  font-family: "Glyphicons Halflings";
  src: url("/maxcdn.bootstrapcdn.com/bootstrap/3.3.6/fonts/glyphicons-halflings-regular.eot");
  src: url("/maxcdn.bootstrapcdn.com/bootstrap/3.3.6/fonts/glyphicons-halflings-regular.eot?#iefix") format("embedded-opentype"), url("//maxcdn.bootstrapcdn.com/bootstrap/3.3.6/fonts/glyphicons-halflings-regular.woff2") format("woff2"), url("//maxcdn.bootstrapcdn.com/bootstrap/3.3.6/fonts/glyphicons-halflings-regular.woff") format("woff"), url("//maxcdn.bootstrapcdn.com/bootstrap/3.3.6/fonts/glyphicons-halflings-regular.ttf") format("truetype"), url("//maxcdn.bootstrapcdn.com/bootstrap/3.3.6/fonts/glyphicons-halflings-regular.svg#glyphicons_halflingsregular") format("svg");
}

.glyphicon {
  position: relative;
  top: 1px;
  display: inline-block;
  font-family: "Glyphicons Halflings";
  font-style: normal;
  font-weight: 400;
  line-height: 1;
  -webkit-font-smoothing: antialiased;
