Hide the menu bar on the top left corner

[Bishu]

I am trying to hide the menu (side navbar) on the left top corner
i use the code as
$('#ew-navbar').hide();

It hide the menu but when there is slow internet and refresh the page
first it shows the menu bar and hide again.

Is there any way to hide from the php code. so that it does not flash when we refresh the page.

You may just add CSS under the HTML > Styles > User tab.

Put this code under the following location "HTML" -> "Styles" > "User" tab:

#ew-navbar{display: none;}
