how to change font style?

There’s a very easy way to remove “Powered by WordPress”, just use the WordPress plugin “WP Hide and Security Enhancer”. This plugin can also change and hide URL, it can even hide your WordPress core files along with login page, theme, and plugin from general site visitors, learned about it on Wpblog, so do check it out. Hope it helps. Thanks
