侧边栏移动到底部

Question

我决定今天开始一个新的个人项目，这是一个论坛类型的东西（仅供练习）。 我设置了基本布局并编写了一些PHP函数，但是当我添加一个新帖子时，侧边栏向下移动并位于帖子下方。

这里的一些图片：

的sidebar.php

<div class ="sidebar"> 

<div class = "col-lg-3 profile-tab sidebar-nav"> 

    <img src="images/dummy-pic.png" alt = ""><br> 
     <a href = "#">USERNAME</a><br> 
     <span>Post count: x</span><br> 
     <span>Likes: x</span> 


</div> 

<div class="col-lg-3"> 
    <ul class="sidebar-nav"> 
     <h4 class = "sb-heading">Post Categories</h4> 
      <li><a href="#">Category Name</a> 
      </li> 
      <li><a href="#">Category Name</a> 
      </li> 
      <li><a href="#">Category Name</a> 
      </li> 
      <li><a href="#">Category Name</a> 
      </li> 
      </ul> 
</div> 

<div class = "col-lg-3"> 
    <ul class="sidebar-nav"> 
     <h4 class = "sb-heading">Announcements</h4> 

      <li>interesting stuff</li> 
      <li>interesting stuff</li> 
      <li>interesting stuff</li> 
    </ul> 
</div> 

Posts.php

<div class = "post col-lg-8"> 

<h2 class = "page-header"><?php echo $post_title; ?></h2> 
<p class = "lead">By 
<a href = "#"><?php echo $post_author ?></a></p> 
<span class = "glyphicon glyphicon-time"><?php echo $post_date ?></span> 

<img class = "img-responsive" src = "<?php echo $post_image; ?>" /> 
<br> 
<p>  
<?php 
echo $post_content; 
?> 

</p> 

<br/> 
<a class = "btn btn-primary" href = "#">READ MORE</a> 

</div> 

<?php } ?> 

有关CSS

.sidebar-nav{ 
background-color: #ffffff; 
margin-top: 15px; 
border:2px solid #1b76bc; 
border-radius: 10px; 
padding: 20px 0 20px 0; 
text-align: center; 


} 

div.post.col-lg-8{ 

margin-left: 20px; 
} 

.sidebar-nav li{ 

    list-style: none; 
} 

.post{ 

padding:15px; 
margin-top: 15px; 
background-color: #ffffff; 
border-radius: 10px; 
border: 2px solid #1b76bc; 
padding: 20px; 

} 

我用COL-LG-3而不是4的侧边栏，这样我可以添加一个左边距的帖子。有可能是更好的方法，但只是一个抬头

如果你需要的css文件让我知道。

我真的很感激它！

请在下面找到工作的例子。小提琴here

.sidebar { 
 
    float: right; 
 
    width: 25%; 
 
    max-width: 25%; 
 
} 
 

 
div.post.col-lg-8 { 
 
    float: left; 
 
    width: 70%; 
 
    max-width: 70%; 
 
} 
 

 
.sidebar-nav { 
 
    background-color: #ffffff; 
 
    margin-top: 15px; 
 
    border: 2px solid #1b76bc; 
 
    border-radius: 10px; 
 
    padding: 20px 0 20px 0; 
 
    text-align: center; 
 
} 
 

 
div.post.col-lg-8 { 
 
    margin-left: 20px; 
 
} 
 

 
.sidebar-nav li { 
 
    list-style: none; 
 
} 
 

 
.post { 
 
    padding: 15px; 
 
    margin-top: 15px;

Answer 2

您必须在Posts.php中关闭div。

编辑：您可以尝试类似下面：

的sidebar.php

<div class ="col-lg-3 col-md-3 col-sm-3 sidebar"> 

<div class = "profile-tab sidebar-nav"> 

    <img src="images/dummy-pic.png" alt = ""><br> 
     <a href = "#">USERNAME</a><br> 
     <span>Post count: x</span><br> 
     <span>Likes: x</span> 


</div> 

<div> 
    <ul class="sidebar-nav"> 
     <h4 class = "sb-heading">Post Categories</h4> 
      <li><a href="#">Category Name</a> 
      </li> 
      <li><a href="#">Category Name</a> 
      </li> 
      <li><a href="#">Category Name</a> 
      </li> 
      <li><a href="#">Category Name</a> 
      </li> 
      </ul> 
</div> 

<div> 
    <ul class="sidebar-nav"> 
     <h4 class = "sb-heading">Announcements</h4> 

      <li>interesting stuff</li> 
      <li>interesting stuff</li> 
      <li>interesting stuff</li> 
    </ul> 
</div> 
</div> 

Posts.php

<div class = "col-lg-8 col-md-8 col-sm-8"> //New line 
// php foreach etc. 
<div class = "post"> 

<h2 class = "page-header"><?php echo $post_title; ?></h2> 
<p class = "lead">By 
<a href = "#"><?php echo $post_author ?></a></p> 
<span class = "glyphicon glyphicon-time"><?php echo $post_date ?></span> 

<img class = "img-responsive" src = "<?php echo $post_image; ?>" /> 
<br> 
<p>  
<?php 
echo $post_content; 
?> 

</p> 

<br/> 
<a class = "btn btn-primary" href = "#">READ MORE</a> 

</div> 

<?php } ?>
