On my homepage of https://hadleylearningcommunity.org.uk/seconday, i have an image of the top part of a phone. i have the image with a 0 bottom margin which sits it at the bottom of the column. However when i resize the browser to see how it looks on tablets / phone etc. the image is not on the bottom of the column any longer and rises up. Can i get the image to always be at the bottom of its column even when resizing?
