如何防止按钮在页面上重叠文本？

Question

我想创建一个按钮，该按钮位于向用户显示的消息下方。 所以我有这个HTML

      <div id="userNotificationsWrapper">

<p>You have no notifications.</p> 

<div><a id="createBtn" data-method="get" href="/user_notifications/new">Create Notification</a></div> 

</div>

然后我的按钮（链接）具有这种样式...

#createBtn {
  margin-bottom: 20px;
  padding: 15px;
  border-radius: 5px;
  border: 1px solid #7ac9b7;
  background-color: #4180C5;
  color: aliceblue;
  text-decoration: none;
  font-size: 15px;
  cursor: pointer;
}

#createBtn:hover {
  background-color: black;
}

但是如果您查看我的演示-https: //jsfiddle.net/7rxdh37h/ ，您会看到该按钮悬停在文本上方，而不是显示在文本下方并停留在内容区域。 我不知道为什么是这样或如何解决它。 有任何想法吗？

Answer 1

首先，您将按钮放在错误的div中。 您需要将其从文本div中移出。 接下来，添加显示块，然后确定按钮/边距区域的大小。

<div id="w">
    <header id="logo">CryptoCurrency Index</header>

    <nav id="navigation">
      <ul>
        <li><a href="#">Home</a></li>
        <li><a href="#">Member Currencies</a></li>
        <li><a href="/user_notifications/" id="notifications">My Notifications</a></li>
    <li id="logout"><a href="/logout">Log Out</a></li>
    </ul>
</nav>

<div id="content">
<div id="userNotificationsWrapper">

<p>You have no notifications.</p> 
</div>
<div class="buttonCreate">
    <a id="createBtn" data-method="get" href="/user_notifications/new">Create Notification</a></div>

.buttonCreate{

  margin: 10px auto;
  display: block;

Answer 2

也许display:table是您想要的。 我只是添加了display:table和margin:auto ，它起作用了：

您也可以使用display:block ，但必须指定宽度。

Answer 3

您应该以这种方式使用按钮：

<a data-method="get" href="/user_notifications/new">
    <div id="createBtn">Create Notification</div>
</a> 

这样，您的按钮将被放置在文本下方

Answer 4

问题在于标签是内联元素，这使得填充不会影响周围的元素。 因此，如果您添加display：inline-block; 它会保持内联，而不会变成块元素的整个宽度，但也会以您要的方式应用填充。

尽管这可以解决问题，但我认为更改@Hahid Boreiri指出的语法/标记实现方式可能更准确。
