Question

我是这里的新手，我仅针对此问题创建了该帐户。我是一名高中学生，我们受命创建一个网站。我正在尝试在导航栏的中间添加该网站的名称，但是尝试了四个小时之后，却一直没能做到。

这是网站：www.turing.gjh.sk/~vano.m/infoot.php

这是我的代码：

  <ul class="navbar-nav mr-auto">
      <li class="nav-item dropdown">

      <a class="nav-link dropdown-toggle" href="#" id="navbardrop" data-toggle="dropdown">
        <i class='fas fa-bars' style='color:#66fcf1'></i> <span class='text' style='margin-left:0.5vh'>.menu</span>
      </a>
      <div class="dropdown-menu text-light animate slideIn">
        <a class="dropdown-item" href="#">Články</a>
        <a class="dropdown-item" href="#">Kontakt</a>
        <a class="dropdown-item" href="#">O nás</a>
      </div>

    </li>

  </ul>
<div class="align-items-center"><h5>infoot<span>.sk</span></h5></div>
<?php
if (!isset($_SESSION['user'])){ ?>
    <ul class="nav navbar-nav justify-content-between ml-auto">
                <li class="dropdown order-1">
                    <button type="button" id="dropdownMenu1" data-toggle="dropdown" class="btn btn-outline-secondary dropdown-toggle">Login <span class="caret"></span></button>
                    <ul class="dropdown-menu dropdown-menu-right mt-2">
                       <li class="px-3 py-2">
                           <form class="form" role="form" method="post" action="infoot.php">
                                <div class="form-group">
                                    <input name="meno" id="emailInput" placeholder="Meno" class="form-control form-control-sm" type="text" required="">
                                </div>
                                <div class="form-group">
                                    <input name="heslo" id="passwordInput" placeholder="Heslo" class="form-control form-control-sm" type="password" required="">
                                </div>
                                <div class="form-group">
                                    <button type="submit" class="btn btn-dark btn-block" name="tlacidlo">Login</button>
                                </div>
                            </form>
                        </li>
                    </ul>
                </li>
                <li class="dropdown order-2">
                    <button type="button" id="dropdownMenu2" data-toggle="dropdown" class="btn btn-outline-secondary dropdown-toggle">Register <span class="caret"></span></button>
                    <ul class="dropdown-menu dropdown-menu-right mt-2">
                       <li class="px-3 py-2">
                           <form class="form" role="form" method="post" action="infoot.php">
                                <div class="form-group">
                                    <input name="meno" id="emailInput" placeholder="Meno" class="form-control form-control-sm" type="text" required="">
                                </div>
                                <div class="form-group">
                                    <input name="heslo" id="passwordInput" placeholder="Heslo" class="form-control form-control-sm" type="password" required="">
                                </div>
                                <div class="form-group">
                                    <button type="submit" class="btn btn-dark btn-block" name="register">Register</button>
                                </div>
                            </form>
                        </li>
                    </ul>
                </li>
    </ul>

<?php }
else{ ?>
    <ul class="nav navbar-nav  ml-auto align-items-center">
    <a class="navbar-brand"><span class='text'>.vitaj, <?php echo $_SESSION['user']; ?></span></a>
    <a href="logout.php"><span class="fas fa-sign-out-alt"></span></a>
    </ul>
<?php } ?>
</nav>

我需要对齐的是这个

<div class="align-items-center"><h5>infoot<span>.sk</span></h5></div>

您想使用Flexbox或Grid在现代工具上做得很好。结帐W3Schools.com，这是一个学习HTML / CSS / Js的好网站。 a link！

<!DOCTYPE html>
<html>

<head>
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <style>
        body {
            margin: 0;
            font-family: Arial, Helvetica, sans-serif;
        }

        .topnav {
                display: grid;
                grid-template-columns: auto auto auto;
                width: 100%;
                margin: 0;
                padding: 0;
                background-color: #444;
        }

        .topnav div {
            float: left;
            color: #FFF;
            text-align: center;
            padding: 14px 16px;
            text-decoration: none;
            font-size: 24px;
            font-weight: 700;
        }
    </style>
</head>

<body>
    <div>
        <h1>TITLE</h1>
    </div>

    <div class="topnav">
        <div>LEFT</div>
        <div>CENTER</div>
        <div>RIGHT</div>
    </div>

<div>
    <h3><strong>BODY MARKUP HERE...</strong></h3>
</div>
</body>

在CSS中使用以下属性：

align-self:center;

如果这不起作用，请尝试更改引导程序类：

justify-content-between至justify-content-center

如何在导航栏中水平对齐三个项目？
