Confusing Syntax Error

Parse error: syntax error, unexpected ‘.’ in /home/dervopms/miosuperhealth.com/wp-content/themes/dyad/inc/customizer.php on line 27

I get this error after I tried to change some code in my customizer.php file. Whenever I try to visit my site or change anything this error occurs.

I know I have to change something via the CPanel but I don’t know exactly what. Here is my customizer.php code:

<?php
/**
 * Dyad Theme Customizer
 *
 * @package Dyad
 */

/**
 * Add postMessage support for site title and description for the Theme Customizer.
 *
 * @param WP_Customize_Manager $wp_customize Theme Customizer object.
 */
function dyad_customize_register( $wp_customize ) {
	$wp_customize->get_setting( 'blogname' )->transport         = 'postMessage';
	$wp_customize->get_setting( 'blogdescription' )->transport  = 'postMessage';
	$wp_customize->get_setting( 'header_textcolor' )->transport = 'postMessage';
}
add_action( 'customize_register', 'dyad_customize_register' );

/**
 * Binds JS handlers to make Theme Customizer preview reload changes asynchronously.
 */
function dyad_customize_preview_js() {
	wp_enqueue_script( 'dyad_customizer', get_template_directory_uri() . '/js/customizer.js', array( 'customize-preview' ), '20130508', true );
}
add_action( 'customize_preview_init', 'dyad_customize_preview_js' );
.is-singular .entry-media {
  display: none;
}
@media screen and (min-width: 960px) {
  .is-singular:not(.home) .site-inner {
    width: 100% !important;
  }
  .has-post-thumbnail.is-singular:not(.home):not(.single-format-image) .entry-header, .has-post-thumbnail .entry-meta .cat-links {
    position: relative;
    background: transparent;
    color: #000 !important;
    width: 100%;
    text-align: center;
  }
  .has-post-thumbnail.is-singular:not(.home):not(.single-format-image) .entry-header a, .has-post-thumbnail.is-singular:not(.home):not(.single-format-image) .entry-header h1, .has-post-thumbnail.is-singular:not(.home):not(.single-format-image) .entry-header a {
    color: #000 !important;
    text-align: center;
  }
  .is-singular.has-post-thumbnail:not(.single-format-image) .entry-posted .posted-info, .is-singular.has-post-thumbnail:not(.single-format-image) .entry-posted .edit-link {
    float: none;
    text-align: center;
  }
   .has-post-thumbnail.is-singular:not(.home):not(.single-format-image) .entry-header {
     padding-top: 3em;
   }
}

Maybe someone can find the error and help me.
