小编Jaf*_*ami的帖子

我尝试在我的计算机上安装 Laravel Homestead。

我已经按照文档进行了操作，昨天我就开始工作了。

 header {
  width: 100%; 
  margin: 0 auto;
}

#logo {
    text-align: center;
}

.nav {
    text-align: center;
}

.nav li {
  display: inline;
  margin-left: 7em;
  margin-right: 7em;
}

/* use media query to change the layout */
@media  (min-width: 768px) {
    body {
        background-color: #f2f2f2;
    }

    .nav {
        margin-top: -42px;
    }

    .nav li:nth-child(1), .nav li:nth-child(2) {
        float: none;
    }

    .nav li:nth-child(3), .nav li:nth-child(4) {
