So I am frustrated, for the last 3 hours I have been trying to set up a background image for my website copying the way the you tube tutorial was done from the Tesla site. I have not been able to do this because I do not know the measurements of the pictures he used on the tutorial. I wonder if someone can tell me what I am doing wrong. I found a button that made the image responsive but I cannot seem to find where it was. When I change the size of the devices the image get lost.
Than you in advance for the help.
