List of Conditional Tags

Conditional Tags are a boolean data type that can be used in your Template Files to alter the display of content depending on the conditions that the current page matches. They tell WordPress what code to display under specific conditions. Conditional Tags usually work with PHP if /else Conditional Statements and have close relation with WOrdPress Template Hierarchy. .

Warning: You can only use conditional query tags after the WP_Query is set up or  with action hook.
