Snippets by IsItWP

Are you looking for a way to remove the automatically generated inline style width? This works on WordPress 3.4 version. Though we recommend to keep your WordPress website up-to-date. But, we have created a quick code snippet that you can use to remove caption inline width in WordPress.


All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:

add_shortcode('wp_caption', 'fixed_img_caption_shortcode');
add_shortcode('caption', 'fixed_img_caption_shortcode');
function fixed_img_caption_shortcode($attr, $content = null) {
    // New-style shortcode with the caption inside the shortcode with the link and image tags.
    if ( ! isset( $attr['caption'] ) ) {
        if ( preg_match( '#((?:<a [^>]+>s*)?<img [^>]+>(?:s*</a>)?)(.*)#is', $content, $matches ) ) {
            $content = $matches[1];
            $attr['caption'] = trim( $matches[2] );

    // Allow plugins/themes to override the default caption template.
    $output = apply_filters('img_caption_shortcode', '', $attr, $content);
    if ( $output != '' )
        return $output;

        'id'    => '',
        'align' => 'alignnone',
        'width' => '',
        'caption' => ''
    ), $attr));

    if ( 1 > (int) $width || empty($caption) )
        return $content;

    if ( $id ) $id = 'id="' . esc_attr($id) . '" ';

    return '<div ' . $id . 'class="wp-caption ' . esc_attr($align) . '" style="width: ' . $width . 'px">'
    . do_shortcode( $content ) . '<p class="wp-caption-text">' . $caption . '</p></div>';

  1. Hello,
    I see your article have been update last week… but in same time it make reference to WP 3.4.
    I have just tried to apply this method, and nothing change.
    So I am wondering,
    Did I do something wrong (what is possible because I am not an expert at all!).
    Or did this technic is not working anymore with WP 5 ?
