CSS Question

Unexpected behaviour of js in repeated actions

I use standart js and jQuery.

I have standart modal window. And since that have the following mehtods.

function closeModal(modal) {
modal.css('display', 'none');
return false;

function openModal(modal) {
modal.css('dislay', 'block');
return false;


And next using in document:

<a href="#ModalAdd" onclick="openModal($('#ModalAdd'))" class="add">Add</a>

First time this modal window, opens and closes in a good way. After closing, I can't open it again.

But next commands:

$('#ModalAdd').css('display', 'block')

$('#ModalAdd').css('display', 'none')

When i use it in browser console, give me needed result.

What issue might it be about?

(I use Ubuntu firfox, if it is important) Thanks

Remove the typo

function openModal(modal) {
    modal.css('display', 'block');
    return false;


Also toggle the display instead.

function Modal(modal){
