Choose three different original images. These can be images you save off your phone, etc. but they must be yours. Save them each as 'image1.jpg', 'image2.jpg' and 'image3.jpg' in the 'images' folder of your local root. Using the element with two tags and one tag, add an image just under the opening

tag in your index.html file that changes on three different breakpoints. Be sure the images are responsive. html folder: index.html Img folder: images.html Img names: image1.jpg image2.jpg...image3.jpg
