3.4 Summary

Perhaps the most fundamental aspect of Cascading Style Sheets is the cascade itself—the process by which conflicting declarations are sorted out and from which the final document presentation is determined. Integral to this process is the specificity of selectors and their associated declarations, and the mechanism of inheritance.

In the next chapter, we will look at the many types of units that are used to give property values their meaning. Once we have completed that discussion, the fundamentals will be out of the way, and you'll be able to learn about the properties used to style documents.
