How Can JavaScript Determine an HTML Element's Display Attribute (block or none)?

Determining Element's Display Attribute Using JavaScript

Question:

Is it feasible to ascertain whether an HTML element's CSS display attribute is set to "block" or "none" using JavaScript?

Answer:

Yes, it is possible to check an element's display attribute using JavaScript. The methodology depends on whether the attribute is defined inline or as part of a CSS rule.

Inherited or CSS Rules:

If the display attribute is inherited from its parent element or specified by a CSS style rule, you must obtain the element's computed style:

return window.getComputedStyle(element, null).display;

Inline Styling or JavaScript Manipulation:

For elements with display styles declared inline or modified via JavaScript, you can retrieve the attribute directly from the element's style property:

console.log(document.getElementById('someIDThatExists').style.display);

This will return a string representing the current display attribute value.
