how do i delete the empty line of text on top of my forum signature

um. title. i made the gif in my forum signature smaller so that it wouldn't scroll so much but there's an empty line above it that you can probably see pretty easily and it makes it scroll more unnecessarily. i would like for as much of the image as possible to be visible without scrolling. ive noticed that not everyone has this problem so How Fix It. putting the text cursor behind the image and pressing backspace does not do anything
