For instance, we write
element.style.display = "none";
to hide the element by setting element.style.display to 'none'.
We write
element.style.display = "block";
To show the element as a block element by setting element.style.display to 'block'.
Or we write
element.style.display = "inline";
To show the element as an inline element by setting element.style.display to 'inline'.
Or we write
element.style.display = "inline-block";
