You will often find blogs that shows the latest post in a different color or applied different CSS tags. Basically you need to Inject some code inside wordpress post listing generation loop. The Loop is used by WordPress to display each of your posts. Using The Loop, WordPress processes each of the posts to be displayed on the current page and formats them according to how they match specified criteria within The Loop tags. Any HTML or PHP code placed in the Loop will be repeated on each post. So we need to find the latest post and define a specific attribute to that post such as a different CSS class.
