I have an image block on the home page of my website, a single image. It looks fine on the desktop version but on the mobile version there is a big white space above the image. This means that visitors will see the title, menu and social media icons, then a large white space, and then only half of the image is visible, have to scroll down to see whole of image. Can I add custom css to fix this? (My other images are in image galleries and don't have this problem.)Any help is much appreciated!
