When we write any new post we get text formatting options like Paragraph, Heading 1,.... Heading 6 and Preformated. How can we add our own style there.

For example I have below css style that I apply very frequently, so just thought it would be good to have my own style named "My Style 1" in the list, which I can quickly select any time if needed.

{ font-size: 30px;
line-height: 37px;
font-weight: 900;
letter-spacing: 1px;
color: #ee609c !important;
text-shadow:1px 1px 2px #0e0741, 1px 1px 1px #ccc;}

Please let me know how is this possible.

First, you need to add your CSS to both your front-end and editor stylesheet.

Next, we'll need to add a selector to the editor. I usually use the style select drop down which is normally disabled, but is perfect for this use case.

 * Add formatting select to WordPress WYSIWYG.
function my_add_style_select_buttons( $buttons ) {
    array_unshift( $buttons, 'styleselect' );
    return $buttons;
add_filter( 'mce_buttons_2', 'my_add_style_select_buttons' );

Finally, you need to add your selector to the options in this new drop down style selector.

 * Customize formatting options for WordPress WYSIWYG.
function my_tiny_mce_before_init_insert_formats( $init_array ) {
    $style_formats = array(
            'block'   => 'span',
            'classes' => 'my-custom-style',
            'title'   => 'My custom style',
            'wrapper' => true,
    // Insert the array, JSON ENCODED, into 'style_formats'
    $init_array['style_formats'] = wp_json_encode( $style_formats );

    return $init_array;

add_filter( 'tiny_mce_before_init', 'my_tiny_mce_before_init_insert_formats' );

Now when you select text and apply "My custom style" you're wrapping the selected text in a span tag with the class my-custom-style.

  • Hi All, may i know what is the block name for paragraph, i tried with 'p' and 'paragraph' but both are not working. array( 'block' => 'p', 'classes' => 'joke1', 'title' => 'joke1', 'wrapper' => true, ), array( 'block' => 'Paragraph', 'classes' => 'joke2', 'title' => 'joke2', 'wrapper' => true, ), Apr 24, 2019 at 12:08

    I don't recommend using paragraph tags since the editor handles those differently. Try using div elements instead. Apr 24, 2019 at 13:15
