我正在寻找一种垂直居中对齐containerdiv的方法,jumbotron并将其设置在页面中间.
在.jumbotron必须适应屏幕的整个高度和宽度,所以我用这个CSS.
.jumbotron {
height:100%;
width:100%;
}
.container {
width:1025px;
}
.jumbotron .container {
max-width: 100%;
} 的.containerdiv有一个宽度1025px和应在该页面(垂直中心)的中间.

我有一个Ubuntu 14.04内核.我在这台服务器上安装了我的Laravel应用程序.安装后,我尝试将根目录设置为public.
sudo nano /etc/apache2/sites-available/000-default.conf
我在文件中只有这些选项
<VirtualHost *:80>
# The ServerName directive sets the request scheme, hostname and port t$
# the server uses to identify itself. This is used when creating
# redirection URLs. In the context of virtual hosts, the ServerName
# specifies what hostname must appear in the request's Host: header to
# match this virtual host. For the default virtual host (this file) this
# value is not decisive as it is used as a last …当我们向下滚动页面并且第二个div遇到顶部边界时,我想坚持第二个div.当它被修复时,它应该与其他页面一起滚动.我怎样才能做到这一点？
#settings{
width:100%;
background:#383838;
height:60px;
}
#menu{
width:100%;
position:relative;
height:100px;
background:#aaa;
}
#body-content{
height:900px;
position:relative;
}
和HTML
<body>
<div id="top">
<div id="settings">
</div>
<div id="menu">
</div>
</div>
<div id="body-content">
</div>
</body>
在这个例子http://jsfiddle.net/WBur3/中,当我们滚动页面时,应该修复第二个div.当我们向上滚动时,应该变成先前的状态本身.请帮我.
我正在尝试使用以下代码从数据库中获取值
$request = Registrationrequest::where('course_id', $id)
->where('user_id', Auth::user()->id)
->where('registered', true)->count();
我正在使用Laravel.我有一排course_id = 4,user_id=3和registered=true.当我分别对var_dump每个值进行var_dump时,我确认了它.但是当我一起使用这个条件时,我没有得到计数值为1,而是得到0.
我有另一个查询,我使用
$request = Registrationrequest::where('course_id', $id)
->where('user_id', Auth::user()->id)
->where('registered', false)->first();
当注册值为false时,这非常有效.
有谁能告诉我哪里错了？
这可能是一个重复的问题,但我无法弄清楚我该怎么做.我正在尝试将一个remoteBranch不是主分支的远程分支合并到我的本地分支localBranch.
我的一位开发人员为远程分支上的api端点添加了一个新分支remoteBranch.作为前端开发人员,我需要获取该分支并将其与我的本地开发分支合并localBranch以利用该api端点.我怎样才能做到这一点？
我按照如何安装Laravel,但毕竟当我进入"vagrant up"时我得到这些错误:

我正在尝试将csv文件上传到usersLaravel中的表格.
这是我的php脚本:
private function _import_csv($path, $filename)
{
$csv = $path . $filename;
$query = sprintf("LOAD DATA local INFILE '%s' INTO TABLE users FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '\"' ESCAPED BY '\"' LINES TERMINATED BY '\\n' IGNORE 0 LINES (`firstname`, `lastname`, `username`, `gender`, `email`, `country`, `ethnicity`, `education` )", addslashes($csv));
return DB::connection()->getpdo()->exec($query);
}
public function uploadUsers(){
if (Input::hasFile('fileInput')){
$file = Input::file('fileInput');
$name = time() . '-' . $file->getClientOriginalName();
$path = 'public/uploads/'.date('Y/m/');
$file->move($path, $name);
$this->_import_csv($path, …我正在尝试创建一个第一行的表单,单个文本字段100%宽度和第2行3个字段等距.它适用于Chrome.然而,它在FireFox上溢出.
.form {
display: flex;
flex-direction: column;
width: 300px;
justify-content: center;
align-items: center;
margin: 0 auto;
}
.form input {
width: 100%;
padding: 20px;
}
.form .number {
width: 100%;
display: flex;
align-items: center;
justify-content: center;

.form .expiry {

<div class="expiry">

<input data-stripe="exp-year" placeholder="YY" class="" type="text">
<input data-stripe="cvc" placeholder="CVC" class="" type="text">
</div>
</div>我用来date-fns返回一些值，如下所示：
import { format, formatDistance } from "date-fns";
var date = new Date("2019-03-06 00:00:00");
console.log(format(new Date(date), "dd MMM, y"));
它在 Chrome 上运行良好并返回We Mar, y
但Invalid Date在 Safari 中返回。
我相信这是因为日期（“2019-03-06 00:00:00”）不是 ISO 8601 格式。但这是我从端点接收的格式。是否有任何选项可以将其转换为正确的格式并使其在 Safari 上运行？
