背景
fastadmin 用习惯了，但是登录界面真的不好看，今天就修改一下。先看界面：
解决方案
1.安装插件：后台登录背景。
2.上传固定图片修改登录页面为如下：
<!DOCTYPE html>
<html>
<head>{include file="common/meta" /}<style type="text/css">body {color: #999;background-color: #f1f4fd;background-size: cover;}a {color: #444;}.login-screen {max-width: 430px;padding: 0;margin: 250px auto 0 auto;}.login-screen .well {border-radius: 7px;-webkit-box-shadow: 0 0 30px rgba(0, 0, 0, 0.1);box-shadow: 0 0 30px rgba(0, 0, 0, 0.1);background: rgba(255, 255, 255, 1);border: none;/*overflow: hidden;*/padding: 0;}@media (max-width: 767px) {.login-screen {padding: 0 20px;}}.profile-img-card {width: 50px;height: 50px;display: block;-moz-border-radius: 50%;-webkit-border-radius: 50%;border-radius: 50%;margin: 0px auto 20px;border: 5px solid #fff;}.profile-name-card {margin: 10px auto 20px;text-align: left;font-size: 20px;font-weight: bold;color:#0d0d0d;}.login-head {background: #899fe1;border-radius: 7px 7px 0 0;}.login-form {padding: 40px 30px;position: relative;z-index: 99;}#login-form {margin-top: 20px;}#login-form .input-group {margin-bottom: 15px;}#login-form .form-control {font-size: 13px;}</style><!--@formatter:off-->{if $background}<style type="text/css">body{background-image: url('{$background}');}</style>{/if}<!--@formatter:on-->
