In this video, we will create a full screen popup for our add link form. This way it does not push down our links list content when the user wants to add a link. This full screen popup can be used in many ways (logins/register forms, loading icons, etc.). It will take up the entire width and height of the window with a semi transparent dark background. This lets the user know that they are unable to interact with anything in the background until loading has finished, they complete a form, etc.
