WordPress Speed Up Service | WordPress Website Maintenance Packages Reply To: How can we achieve this image css style?, by paulwpxp I would use CSS’s pseudo elements ::before or ::after, and add in the image as CSS Content, then position it at lower right. There might be adjustment with z-index making sure it’s over the main image. There is no need to go over the image just to manually add in the class. We can make use of WP’s auto generated post class. In this case you have that kind of posts categorized as “tricky”. There we have this class .category-tricky to help target the image used in the post. Reply To: How can we achieve this image css style?
