By now you should be getting pretty comfortable creating simple OpenLayers maps with a combination of raster and vector data. With raster data, there is no control over presentation, as the saying goes–what you see is what you get. Vector data, on the other hand, gives you direct control over presentation details. We've already alluded to vector styles, and used them in the previous chapter. Now, it is time to take full control of how we present our vector data!
In the last chapter, you saw how powerful the vector layer can be. In this chapter, we'll go a bit deeper and talk about how to customize the appearance of the features within a vector layer. We'll explore the following:
The basic style object
Fill, stroke, image, and text styles
Composing multiple styles
Using style functions
Applying styles interactively
