我的问题

我希望菜单项按内联顺序排列(彼此相邻)，就像原始菜单一样，但宽度为 1400 像素或 100%，菜单项位于中间。

您可以使用 display:flex 来达到这个目的。检查下面的解决方案，这里是 fiddle

.nav,
.nav a,
.nav ul,
.nav li,
.nav div,
.nav form,
.nav input {
    margin: 0;
    padding: 0;

    outline: none;
}

.nav a { text-decoration: none; }

.nav li { list-style: none; width:100%; }

/* Menu Container */
.nav {
    display: flex;
    position: relative;
    cursor: default;
    z-index: 500;
}

/* Menu List */
.nav > li {
    float: left;
}

/* Menu Links */
.nav > li > a {
    position: relative;
    display: inline-flex;
    width: 100%;
    z-index: 510;
    height: 54px;
