我正在尝试在我的网站的登录框中显示文本“用户名”右侧的图标或.png，但是我无法显示它。我练习制作一个简单的html页面，我可以将它显示在一个简单页面的屏幕上，但是当我用我的登录页面尝试时，它无法显示在“用户名”旁边。我尝试将.png和.ico的代码放在“用户名”旁边，并在相关标题下的.css文件中，但无法显示。 .png和.ico文件位于根文件夹中。我已经阅读并观看了许多教程，尝试了许多不同的代码示例等。任何建议都将不胜感激！
我尝试过这段代码没有运气：
<img src = 'sunny.png' style='vertical-align: middle' />
我的登录HTML代码：
$(document).ready(function () {
$('#logo').addClass('animated fadeInDown');
$("input:text:visible:first").focus();
});
$('#username').focus(function() {
$('label[for="username"]').addClass('selected');
});
$('#username').blur(function() {
$('label[for="username"]').removeClass('selected');
});
$('#password').focus(function() {
$('label[for="password"]').addClass('selected');
});
$('#password').blur(function() {
$('label[for="password"]').removeClass('selected');

CheatSheet：placeholder=" Username"
和input { font-family: 'FontAwesome'; }进入 css
