请查看此 css 和 html，然后查看图像以了解我所说的差距。我可能对一些太小的事情大惊小怪，修复这个问题不会对网页的可用性产生任何影响，但我现在正在学习，我只想了解这种行为。

我附加了两个 css 文件，一个是我的重置文件，另一个是这个页面的:

box-sizing:border-box;
word-wrap:normal;
}
article, aside, details, figcaption, figure, footer, header, hgroup, menu, nav, section {
display: block;
}
body {
line-height: 1.2;
}
ol {
padding-left: 1.4em;
list-style: decimal;
}
ul {
list-style: square;
}
table {
border-collapse: collapse;
border-spacing: 0;
}
table, th, td {
border: 1px solid black;
}
a{
color:black;
cursor:pointer;
text-decoration: none;
}
a:active{
color:inherit;
}
input[type="submit"] {
float: left;
padding: 4px 8px;
border: 1px solid rgb(50,50,50);
font-size: .8em;
}
主文件(对于本页):
#navmenu ul li{
display:inline-block;
padding:15px;
}
#navmenu ul{
display:inline-block;
}
#topbar a {
float: right;
display: inline;
padding: 5px;
}
#navmenu {
display:inline-block;
float: left;
}
#navmenu ul li:hover {
background-color: rgb(50,50,50);
color: rgb(255,255,255);
}
现在这是浏览器中导航菜单的图像，请注意 li 元素之间的间隙。我已经更改了显示属性，如果这是某种边距，我已经在 chrome 中进行了检查，但是当我检查元素时，它并没有真正告诉我差距是什么。
