Question

您好我是编码的新手，我在家里自学。我遇到了一个我根本无法解决的问题。

首先，这是该网站的codepen链接：

除一个问题外，该网站的工作非常顺畅。

看一下＆＃39;项目＆＃39;列表左侧的列表。我已经设置它，以便在悬停时字体颜色，背景颜色和字体大小发生变化（我必须更改填充以确保li保持相同的大小）。当屏幕尺寸大于900px时，此工作正常。

现在我已使页面响应并设置媒体查询以将布局更改为低于900px。项目列表移动到页面顶部，其格式为新格式，而不是单个列。除了每行右侧的最后一项（第3项和第6项）外，这看起来工作正常。每当我将鼠标悬停在它上面时，它会将下一个项目向右推动两个空格，留下两个空格。我正在使用的一个HTML编辑器显示存在两个＆＃34; ghost＆＃34;那些没有的物品。

任何猜测？

我也对该网站的任何评论或批评持开放态度，渴望学习。

这是原始代码

Answer 1

解决此问题的最简单方法是为font-size:23px;

设置.sidebar a:hover

.sidebar a:hover{
    color:lightgray;
    background-color:coral; 
    font-size:23px;
    padding:10px 0;      
}
