Sometimes it can be hard to make a menu close after it has been clicked on, especially if the viewport has been narrowed so that the 'hamburger' is the icon to open it with, and if there is a link going to a section further down on the same page. This has been remedied here with a bit of java script. The menu item 'anchor' is such a link, and when clicked on, it will take you to an image on this page, below these comments. Try it with a narrow viewport!
To edit the menu with the black background, find the container with the class name .dark.
The menu has a width limitation of 1200px which can be changed - or removed. If you want to change the logo, you can use most anything up to 75px height without having to alter any other settings. Beyond that, you will need to play with the height and padding of the .menu-topwrap container.
This even works in IE11.
Download the component.
