HTML中的圖標未顯示在網頁上嗎?

[英]Icon in HTML is not showing up on webpage?

我試圖在我的網站的登錄框中使圖標“ .png”顯示在文本“用戶名”的右側,但是我無法顯示它。 我練習了制作一個簡單的html頁面,我可以將其顯示在一個簡單頁面的屏幕上,但是當我在登錄頁面中嘗試該頁面時,卻無法使其顯示在“用戶名”旁邊。 我嘗試將.png和.ico的代碼放在“用戶名”旁邊,並在關聯的標題下的.css文件中,但是無法使其顯示。 .png和.ico文件位於根文件夾中。 我已經閱讀並觀看了許多教程,嘗試了許多不同的代碼示例,等等。任何建議將不勝感激!

我試過沒有運氣放置此代碼:

<img src = 'sunny.png' style='vertical-align: middle' />

我的登錄HTML代碼:

 $(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'); });

嘗試添加:

字體真棒 CSS URI

CheatSheetplaceholder="&#61447; Username"

input { font-family: 'FontAwesome'; } input { font-family: 'FontAwesome'; }放入您的CSS

 $(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'); });
