It seems that you cannot directly control the space between the list-style (or brand) and whether the content is.
For this to happen, you can use the image as a background
li { list-style-type: none; background-image: url('http://placehold.it/50x40'); background-repeat: no-repeat; background-size: 15px 15px; padding-left: 15px; }
