Perhaps some of you don’t like the default fonts of WordPress Editor, you can change it to your favorite fonts by copying and pasting some short code in your functions.php file.

add_action( 'admin_head-post.php', 'devpress_fix_html_editor_font' );
add_action( 'admin_head-post-new.php', 'devpress_fix_html_editor_font' );

function devpress_fix_html_editor_font() { ?>
<style type="text/css">#editorcontainer #content, #wp_mce_fullscreen { font-family: Georgia, "Times New Roman", "Bitstream Charter", Times, serif; }</style>
<?php }
