How to show or hide an element:
In order to show or hide an element, manipulate the element's style property. In most cases, you probably just want to change the element's display property:
element.style.display = 'none'; // Hide
element.style.display = 'block'; // Show
element.style.display = 'inline'; // Show
element.style.display = 'inline-block'; // Show
Alternatively, if you would still like the element to occupy space (like if you were to hide a table cell), you could change the element's visibility property instead:
element.style.visibility = 'hidden'; // Hide
element.style.visibility = 'visible'; // Show
