4-10-24 Notes

            
element.classList.add('classNameHere') adds a class to an element
vh = height of the viewport (the size of the actual page) in percent. EX: 100vh = 100% viewport height. 50% vh can be different from 50% height
z-index: 1. EX: The higher the z-index, the closer the element is to the screen. An element with z-index 1 will be "on top of" an element with z-index 2
overflow: hidden. Makes an element unable to have content that overflows out of the element's designated space.
Professor let me leave class early, so this is where today's notes end.
