<p>Hi there! Boxes like these are created through Templates, which require html or css knowledge to code (you can read more by clicking the link). You can find a lot of precoded boxes online by googling for premade css codes, however, more advanced boxes like on the Steven Universe wiki are usually a bit tough to code if you don't have at least base css knowledge. Your options are to either try to study css or perhaps try to find someone who may be so kind to code templates for you! Hope that helped to explain it some! c= </p>
