Assign an ARIA state of "hidden" to the label, like this: <label state="hidden">Search</label> <input type="text" name="search" id="search" />

Use the built-in WordPress CSS class .screen-reader-text to hide the text from screen, like this: <label class="screen-reader-text">Search</label> <input type="text" name="search" id="search" />

Create a custom CSS class to set a large negative value to the text-indent property to hide the text off screen, like this: <label class="hide-this">Search</label> <input type="text" name="search" id="search" />

The majority of users do not require a screen reader. Remove the label entirely.

37. You might see this code in a WordPress plugin. What does it do?

if ( ! defined( 'ABSPATH' ) ) {

die;

}

This is how WordPress detects a plugin's presence. This ensures that the plugin is running from the /wp-content/plugins/ directory. If it is not, the plugin should not run.

This is a way to prevent naming collisions. ABSPATH is the absolute path to the plugin's directory. If ABSPATH is defined by another WordPress plugin with the same directory slug, the plugin should not run.

This is a security measure. ABSPATH is the absolute path to the WordPress directory. If the file is called directly, ABSPATH will not be defined and therefore the plugin should not run.

This is a compatibility checker. ABSPATH is defined in WordPress core. The plugin checks that the minimum version of WordPress needed to support the plugin is installed. If it is not, the plugin should not run.
