On my website, I have a simple navigation bar located at the top with just two links. However, when the view switches to mobile (tablet and/or smartphone), these links disappear and are replaced by a "hamburger" menu icon. The issue arises when I click on this icon, nothing happens. I want both of my links to be visible when I click on the menu icon.
