任何想法,为什么我的字体可怕的图标最初显示在页面上,然后变成空白方块一旦页面实际加载？这是我的宝石文件：
gem 'rails','4.0.1' gem 'bootstrap-sass','2.3.2.0' gem 'bcrypt-ruby','3.1.2' gem 'faker','1.1.2' gem 'will_paginate','3.0.4' gem 'bootstrap-will_paginate','0.0.9' gem "libv8",">= 3.11.8" gem "therubyracer",">= 0.11.0",:group => :assets,:platform => :ruby,:requir\ e => "v8" gem 'execjs' gem 'rails_12factor',group: :production gem 'font-awesome-rails' gem 'font-awesome-sass'
我的application.css文件：
*= require_self *= require_tree . *= require font-awesome */ @import 'twitter/bootstrap'; @import 'font-awesome/font-awesome';
以下是我打电话给图标的方式：
<section id="our-services" class="pad-top-50">
<div class="container">
<div class="row">
<div class="col-xs-12 col-sm-4">
<div class="service">
<span class="service-icon">
<i class="fa fa-android"></i>
</span>
