From the WordPress Dashboard, go to Appearance > Themes.
Click Add New and browse themes.
Install and Activate the one you like.
Use the WordPress Customizer (Appearance > Customize) to adjust colors, fonts, and layouts.
Open Elementor to build fully custom pages with drag-and-drop design.
Choose lightweight themes for faster loading.
Always use a theme that is regularly updated.
Note: Switching themes wonโt delete your content, but layouts may change. Test on a staging site first if possible.
