User Contributed Notes

  1. Skip to note 6 content

    Add more classes.
    You can add a class to the post_class defaults:

    <div id="post-<?php the_ID(); ?>" <?php post_class( 'class-name' ); ?>>

    The above prints HTML with your added class and the defaults:
    [html]<div id="post-4564" class="class-name post-4564 post type-post status-publish format-standard hentry category-news">[/html]

    Use an array to add multiple classes:

    $classes = array(
    <div id="post-<?php the_ID(); ?>" <?php post_class( $classes ); ?>>

    Example of the template tag (and its default CSS classes).
    This example shows the post_class template tag as commonly used in a theme file (such as single.php):

    <div id="post-<?php the_ID(); ?>" <?php post_class(); ?>>

    The output of the above prints this HTML (for a post in the ‘news’ category and a theme that supports Post Formats):
    [html]<div id="post-4564" class="post-4564 post type-post status-publish format-standard hentry category-news">[/html]

    Using these CSS classes you can then style this specific post, or all posts assigned the same category (or post format):

    .post {
    	/* Styles for all posts */
    .post-4564 {
    	/* Styles for only this post (ID number 4564) */
    .category-news {
    	/* Styles for all posts in the 'news' category  */
    .format-standard {
    	/* Styles for all posts assigned the post-format of 'standard'  */
