我正在为工作朋友免费制作一个网站，显然我的知识和经验有限，这就是我在这里寻求帮助的原因。

我不确定是否需要 .js 文件或 .css 文件才能使 onmouseover 工作；我现在完全没有想法了。

如果您是新手，您可能应该尽量避免使用冗长的 JavaScript，因为您将很难管理它。相反，我鼓励您从图像属性开始，例如onmouseoverand onmouseout。考虑以下：

<!DOCTYPE html>
<html>
    <head>
        <meta charset="UTF-8">
        <title>Hover-Fading Buttons</title>
        <base href="http://parkleyvisualarts.com/" />
        <style>
            img.logo {
                width: 300px;
                height: 300px;
                display: block;
                margin: 0 auto;
            }
        </style>
    </head>
    <body>
        <img src="Minilogo.gif" class="logo"
             onmouseover=" this.src = 'Eyewinker.gif' " 
             onmouseout=" this.src = 'Minilogo.gif' " />
    </body>
</html>
