To automatically create full-width responsive YouTube videos in WordPress CMS using Angkor Design website design and mobile app development, we will provide a step-by-step guide. By following these steps, you can seamlessly integrate your YouTube videos into your WordPress website, improving the user experience for your visitors. Let’s begin!

1. Using a WordPress Plugin

1. Install a Plugin: Install a plugin like “Advanced Responsive Video Embedder” or “WP YouTube Lyte” from the WordPress plugin repository.
2. Activate the Plugin: Once the plugin is installed, activate it from the WordPress dashboard.
3. Configure Settings: Configure the settings of the plugin to enable full-width and responsive YouTube embeds. Most plugins offer options to automatically make YouTube embeds responsive and full-width.
4. Insert YouTube Embed: After configuring the settings, simply insert the YouTube URL into your post or page. The plugin should automatically make the embed full-width and responsive.

2. Using Custom Code

If you prefer to handle this without a plugin, you can achieve the same result using custom code.

1. Access the Theme Editor: In the WordPress dashboard, go to “Appearance” and then “Theme Editor”.
2. Edit the Theme’s CSS: Locate the “style.css” file or the file where the CSS is defined for your theme.
3. Add CSS Code: Add the following CSS code to make the YouTube embeds full-width and responsive:

   .entry-content iframe { width: 100%; height: auto; }

4. Save Changes: Save the changes you made to the CSS file.

3. Add code to your functions.php and CSS

Insert the following code into your theme by adding it to your functions.php file

1. Add this code to your functions.php

/** * Add Response code to video embeds in WordPress * * @refer http://alxmedia.se/code/2013/10/make-wordpress-default-video-embeds-responsive/ */ function abl1035_alx_embed_html( $html ) { return '<div class="video-container">' . $html . '</div>'; } add_filter( 'embed_oembed_html', 'abl1035_alx_embed_html', 10, 3 ); add_filter( 'video_embed_html', 'abl1035_alx_embed_html' ); // Jetpack 

2. Add this to your stylesheet “style.css”

/*---------- Video Embeds ---------*/
  
.video-container { 
  position: relative; 
  padding-bottom: 56.25%; 
  height: 0; 
  overflow: hidden;
  max-width: 1200px;
  margin: 0 auto;
}
  
.video-container iframe, .video-container object, .video-container embed, .video-container video { 
  position: absolute; 
  top: 0; 
  left: 0; 
  right: 0;
  width: 100%;
  height: 100%;
}

You can adjust or remove the max-width as necessary.

By following these steps, you can ensure that YouTube embeds in your WordPress CMS are automatically full-width and responsive, providing a better viewing experience for your visitors.
