Add jQuery to soccerslicknav.html
Add jQuery code to soccerslicknav.html to call Slicknav on the appropriate menu. You may want to attach the menu to an element other than the default body element.
Update style.css to show and hide menus as appropriate for desktop and mobile browsers. You may also want to update the look of the Slicknav menu: try changing the background color or other aspects of the menu.
Test your work in both a desktop and mobile browser.
