I a plugin that I have made (SNUP Widget) there is a strange error.
When I use widescreen monitor this custom meta box I made looks ok. But with I open browser on my PC with split screen that is not widescreen then the metabox size is showing up strange.
See the screendump.

enter image description here



Here is the code for the metabox:

function snup_add_meta_box(){
    add_meta_box (
        'snup_id', //id
        'Show Next Upcoming Post', //title
        'snup_callback', //callback
        'post', //screen
        'normal', //context
        'default', //priority

    );
}
add_action('add_meta_boxes', 'snup_add_meta_box');


function snup_callback($post){ 
    wp_nonce_field('snup_meta_box', 'snup_meta_box_nonce');

$snuptext = get_post_meta($post->ID, 'snuptext', true);
$label1=__('Please type the teaser text here','snup-lang');
$label2=__('Max 100 characters.', 'snup-lang');

?>
    <p>
    <label><b><?php echo esc_html_e($label1);?></b></label><br>
    <label><?php echo esc_html_e($label2);?></label><br>
    <textarea style="resize:none" name="snuptext" rows="3" cols="100%" maxlength="100"><?php echo esc_textarea($snuptext);?></textarea>
    </p>

all you need to do is cols="40", any size you want. I am not sure if WordPress provides class for this but you can also use inline CSS style="width: 100%; box-sizing:border-box; -moz-box-sizing:border-box;" or add this CSS to admin style.
