Small fonts on WordPress backend post pages!How to change font size.

Are the fonts on WordPress back-end post pages too small?

In such cases, this is.

If you write all this down, you can customise the font size and other aspects of the posting page (text) as you wish.

Please add this to the ‘functions.php’ of the theme (or child theme when using a child theme).

function wp_admin_textarea() {
echo 'textarea.wp-editor-area{font-size:17px !important;line-height:1.8em !important;}';
}
add_action('admin_head', 'wp_admin_textarea', 100);

Change the size, height and space to your liking.
