【问题描述】：

我做了一个进化计算器，我一直想出这个基本上，您单击按钮，计算机会提示您两次，并根据用户对提示的回答来增加一些内容...我对 HTML 相当陌生，所以..

这是我的代码

请在问题上发布您的错误消息。您可以将图像插入问题本身。

标签： html css if-statement button runtime-error

【解决方案1】：

您的错误只是说您的服务器上没有favicon.ico。这与您的代码无关。默认情况下，html 会在 / 上查找名称为 favicon.ico 的网站图标。由于它没有找到它，并且您没有声明在其他路径和/或使用其他名称搜索它，它会在控制台上引发 404 错误。更多关于为什么要指定它的信息可以找到here。

只要确保添加声明或将文件放在那里，就不会再出现该错误。

除此之外，您的代码似乎工作正常 :)
