sidebar moving to the bottom

Question

I decided to start a new personal project today which is a forum type of thing (just for practice). I set up the basic layout and wrote some of the PHP functions but when I add a new post, the sidebar moves down and underneath the posts.

here's some pics:

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 } ?>

relevant 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;

}

I used col-lg-3 instead of 4 for the sidebar so that I could add a left margin to the post. There's probably a better way but just a heads up

If you need the css file let me know.

I really appreciate it!

Answer 1

You must close div in Posts.php.

Edit: Can you try something like below:

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 } ?>
