WP How can I modify a particular thumbnail size with a custom CSS class?

I have been attempting to use add_image_size for my custom thumbnail resize, but it seems to be having trouble maintaining the thumbnail size at 220 x 220. Instead, it keeps changing the height to 167 pixels. As a workaround, I am exploring a CSS-based solution, which should work seamlessly.

This is my current thumbnail code:

<?php if ( ! post_password_required() && ! is_attachment() ) :
            the_post_thumbnail(); 
        endif; ?>

Below is the CSS class that I am seeking assistance in applying to the thumbnail code above:

.imgclass{
height: 220px;
width: 220px;
}

Big thanks to all the amazing coders out there!

Answer №1

To add a custom CSS to the thumbnail URL, you can follow these steps:

<?php $url = wp_get_attachment_url(get_post_thumbnail_id($post->ID)); ?>
<img src="<?php echo $url; ?>" class="thumbnail_image"/>

Answer №2

Make sure to specify the size of the image you want to use as the thumbnail.

<?php if ( ! post_password_required() && ! is_attachment() ) :
    the_post_thumbnail('CUSTOM IMAGE SIZE'); 
endif; ?>

If you prefer, you can also completely reset the default thumbnail size like this:

add_theme_support( 'post-thumbnails' );
set_post_thumbnail_size( 220, 220 );

Answer №3

<?php if ( ! post_password_required() &&& ! is_attachment() ) :
            $thumb_attributes = array( 'class' => "imgclass") ;
            the_post_thumbnail($thumb_attributes); 
      endif; ?>

This code should be effective.
