Plugin Style Replacement
Change the style of your posts with options drop down menu. You can also implement a blog-azine with a different style in every post. This plugin helps you simplify replacement (the template single post) with a dropdown menu. You must create a new template with a structure and a single post with a different style. If no Single post template is selected, the default template will be used.
Upload the entire single-post-template folder to the /wp-content/plugins/ directory. Activate the plugin through the ‘Plugins’ menu in WordPress. Create Post Templates in your theme’s folder.
After you have installed the plugin, you’ll need to create some Post Templates with a structure and a single post with a different style to use. Insert the following code at the very top of the file:
<?php /* Style : [Your Template Name] */ ?>
