WordPress themes under the GPL (General Public License) offer users the flexibility to customize and distribute themes freely. These themes are designed to enhance the visual appeal and functionality of WordPress websites, providing pre-built designs for blogs, business sites, portfolios, eCommerce stores, and more. GPL themes can be modified to meet specific needs, offering customization of layouts, colors, typography, and more. Many themes are available for free, but premium versions often offer advanced features, support, and regular updates. While GPL themes are flexible, some versions from third-party platforms may lack official support and updates from the original developers.
