The Tag and Class Replace plugin offers a simple yet powerful way to modify HTML structure across your WordPress site without touching the core code. As seen in the settings interface, you can effortlessly replace any HTML tag or CSS class with your desired alternatives. For example, you might want to update all occurrences of .header-info h3 to use an h4 tag instead—this can be done quickly by defining the selector and your new tag. Similarly, you can change CSS class names, like replacing .card-box with .card-sm-box, helping you maintain consistency or adapt to a new design system.

This tool allows you to create unlimited rules by adding multiple rows for tag or class replacements. It’s ideal for developers and designers who need to standardize HTML output or restructure content styles without editing theme files or templates. With just a few clicks, you can save settings and apply these changes site-wide. Whether you’re updating semantic markup for accessibility or adjusting styles for a redesigned frontend, the Tag and Class Replace plugin streamlines the process and reduces the risk of manual error. It’s a great solution for maintaining clean, up-to-date code across your WordPress project.
