function nextandpre-posts-display($content) {
     if (is_single())  {
	 $nextandpre = '<div class="previous">
	 .previous_post_link('<strong>%link</strong>');
	 </div>';
	 return $content . $nextandpre;
}
     return $content;
}
function nextandpre-posts-style()
{
    // this is where we'll style our box
    echo
    '<style type="text/css">
  .previous {
        border: 1px solid #bbb;
        background: #eee;
        padding: 5px;

    Okay..

    1. You CANNOT use hyphens in function names. Use underscores instead.

    2. You In your first function, you are improperly using single and double quotes when “blending” in and out of php and html.

    Try this code instead:

    function nextandpre_posts_display($content) {
     if (is_single())  {
	 $nextandpre = '<div class="previous">
	 .previous_post_link("<strong>%link</strong>");
	 </div>';
	 return $content . $nextandpre;
}
     return $content;
}
function nextandpre_posts_style()
{
    // this is where we'll style our box
    echo
    '<style type="text/css">
  .previous {
        border: 1px solid #bbb;
        background: #eee;
        padding: 5px;
    }
    </style>';
} 

add_action('the_content', 'nextandpre_posts_display');
add_action('wp_head', 'nextandpre_posts_style');

    Try using a code editor like Adobe Dreamweaver or NotePad++… they will let you know when you are using improper code.

    you seem to be trying to concatenate the previous post link with some html;
    that won’t work because previous_post_link() prints the result;
    http://codex.wordpress.org/Function_Reference/previous_post_link

    you would need to use a function which would return the link;
    for example build the link using http://codex.wordpress.org/Function_Reference/get_previous_post

    example, building on the revised code by @josh:

    function nextandpre_posts_display($content) {
     if (is_single())  {
	 $nextandpre = '<div class="previous">';
	 $prev_post = get_previous_post();
	 if (!empty( $prev_post )):
	 $nextandpre .=  '<a href="' . get_permalink( $prev_post->ID ) . '">' . $prev_post->post_title . '</a>';
	 endif;
	 $nextandpre .= '</div>';
	 return $content . $nextandpre;
}
     return $content;
}

    similar for ‘next_post_link’ which is missing at the moment … (?)

    Thanks @alchymyth. I didn’t have a chance to look at the actual code as I was in a hurry. Thank you for the additional info!

    Thanks @josh, @alchymyth it’s really helpful… And it worked.
