php - 如何在 PHP 中使用 Bootstrap Grid

问题描述

基本上，我想让这个页面具有响应性，以便仅使用引导网格（容器、行、列）在移动设备上轻松查看，而不使用引导程序的样式。尽管我尝试了很多方法，但现在它并没有这样做。我的其他没有 PHP 的页面并没有给我带来太多麻烦，但是这个页面有，我无法让它在手机上很好地显示。

我尝试从页面顶部的容器开始，在 php 块之外，然后为我的 h2 标签创建一行，并尝试在我的 while 循环中做同样的事情。但是，它没有响应，结果和列标题没有正确对齐。

“headerprofile.php”

解决方案

鉴于您所展示的内容，您至少需要移动 headerprofile.php 包含，以便它在<head>标签内呈现：

<?php
require_once('includes/database.php');
?>

<!doctype html>
<html>
     <head>
        <?php require_once('includes/headerprofile.php'); ?>

        <style>
            form.searchbar {
                margin: 25px 50px;
            }

            h1.profile {
            margin: 25px 50px;
            }
            h2 {     
              margin: 20px 45px;
            }
            h1 {     
               text-align: center;
            } 

            p {
              margin: 20px 45px;
            }

            .responsive {
              width: 100%;
              height: auto;
            }

            body {margin: 0;}

            ul.nav {
              list-style-type: none;
              margin: 0;
              padding: 0;
              overflow: hidden;
              background-color: rgb(119,13,41);
            }


            ul.nav li {float: left;}

            ul.nav li a {

              color: white;

            }

            ul.nav li a.active {
                background-color: rgb(169,5,51);
            }

            ul.nav li.right {
                float: right;
            }

            @media screen and (max-width: 600px) {
              ul.nav li.right, 
              ul.nav li {float: none;}
            }

            .table  { 
                display: table;
                margin-left: auto;
                margin-right: auto;
                text-align: left;
            }
            .tr{ 
                display: table-row; 
                padding: 7px;
            }
            .td{ 
                display: table-cell;
                padding: 7px;

我还清理了一些无效的标记（标签内的 div 等）。
