In this video we'll talk about creating of styles for layers in geoserver using language SLD, i.e. Style Layer Descriptor. In fact, it's writing of xml-file according to certain instructions. They are listed in the tutorial for writing of SLD-styles for geoserver. So we can create styles of points, lines, polygons, rasters, we're able to design various rules in this styles, i.e. refer to concrete attribute values in attribute table of your uploaded layer.
