如何使为Firefox浏览器开发的网站与Safari和Chrome兼容?

首先,我对Web开发不是很有经验。我知道的足够多,但是,当我获得浏览器兼容性时,我会感到挣扎。我试图弄清楚为什么Chrome和Safari在读取我的网站代码时是如此不同。我了解不同的浏览器以不同的方式读取代码,但是一段时间以来我一直在试图找出如何解决此问题的方法,但我无法解决。

我希望至少可以弄清楚为什么菜单在Safari浏览器中位于左侧,而不是在Firefox浏览器中位于右侧。如果我发现了这一点,我认为它可以帮助我弄清楚如何清理其余的代码,使其看起来像在Safari浏览器中一样。我一直在尝试找出如何正确实现Webkit的方法,但是我还不知道该怎么做。

它看起来像这样的原因之一是因为我在PC上使用的是Safari,这可能会使Safari版本看起来像在计算机上一样。以下是登录页面的屏幕截图以及它们在Firefox和Safari上的外观:

Safari Version

这是顶部导航栏的HTML代码。

<nav class="navbar-fixed-top">
<a href="index.html"><img id="logo" src="images/core-logo.png" alt="logo" height="46" width="176"></a>
<div id="wrapper">
    <div class="circle icon">
        <h1 id="menuTitle">Menu</h1>
        <span class="line top"></span>
        <span class="line middle"></span>
        <span class="line bottom"></span>
    </div>
</div>
<div class="navigation">
    <ul id="nav-list">
        <li><a href="index.html">Home</a></li>
        <li><a href="about.html">About Us</a></li>
        <li><a href="team.html">Team</a></li>
        <li><a href="services.html">Services</a></li>
        <li><a href="portfolio.html">Portfolio</a></li>
        <li><a href="contact.html">Contact</a></li>
    </ul>
</div>
</nav>

这是上面HTML段的CSS代码。
