How to use CSS Display Property In Javascript

Make a card with the main heading, subheading, paragraph, and button. Give a specific style to all the elements. The JavaScript function togglelement() is called when the user clicks the button. It gets the div element with the id myparagraph. It checks the current display property using the if-else of the div. If the value is none, it changes it to block to make it visible. Refer to the CSS Display Property article for the detailed description.
