html - 带有标签的引导按钮不会组合在一起

Question

首先，我对 HTML 比较陌生，所以这可能很简单。

<div class="btn-group pull-center" style="text-align:center">
        <button class="btn btn-large btn-primary" type="button">Home</button>
        <button class="btn btn-large btn-primary" type="button">Forum</button>
        <button class="btn btn-large btn-primary" type="button">Bans</button>
        <button class="btn btn-large btn-primary" type="button">Store</button>  
    <?php
        if($_SESSION['isLogged'] == true) {
            $username = $_SESSION['username'];
    ?>  <a href="logout.php"><button class="btn btn-large btn-primary" type="button">Hello, <?php $username ?></button></a>
        <a href="logout.php"><button class="btn btn-large btn-primary" type="button">Log out</button></a>

    <?php    }else {
    ?>  <a href="login.php"><button class="btn btn-large btn-primary" type="button">Log in</button></a><?php
        }           

        ?>
    </div>

通常 btn-group 类有效并且他们分组。但是，如果我将 A 标记添加到按钮，则该按钮将不会分组。

Answer 1

这应该适用于引导程序。我这里没有按钮：

<div class="btn-group">
  <a class="btn">Home</a>
  <a class="btn">Forum</a>
  <a class="btn">Bans</a>
  <a class="btn">Store</a>
  <a href="logout.php" class="btn">Hello username</a>
  <a href="logout.php" class="btn">Log out</a>
  <a href="login.php" class="btn">Log in</a>
</div>

Answer 2

您将 .btn 类放在<a>标签内。但是，只有当.btn元素是.btn-group. 事实上，规则可能会写成.btn-group > .btn.

将.btn类放在您的<a>标签上，甚至删除这个无用的按钮标签，它就会起作用。例如：

<div class="btn-group pull-center" style="text-align:center">
  <a class="btn btn-large btn-primary" type="button">Home</a>
  <a class="btn btn-large btn-primary" type="button">Forum</a>
  <a class="btn btn-large btn-primary" type="button">Bans</a>
  <a class="btn btn-large btn-primary" type="button">Store</a>  
  <a href="" class="btn btn-large btn-primary" type="button">Hello, Username</a>
  <a href="logout.php" class="btn btn-large btn-primary" type="button">Log out</a>
</div>

Answer 3

不要使用按钮，只需将btn类添加到a标签中即可。例子：

<div class="btn-group pull-center" style="text-align:center">
  <a class="btn btn-large btn-primary">Home</a>
  <a class="btn btn-large btn-primary">Forum</a>
  <a class="btn btn-large btn-primary">Bans</a>
  <a class="btn btn-large btn-primary">Store</a>  
  <a href="logout.php" class="btn btn-large btn-primary">Hello, Username</a>
  <a href="logout.php" class="btn btn-large btn-primary">Log out</a>
  <a href="login.php" class="btn btn-large btn-primary">Log in</a>
</div>
