Appendix A. Resources

When working with Cascading Style Sheets, keep these two tips in mind: simplify and verify. Simplify by using only the selectors and properties you believe you need; any extras could cause some confusion down the road. Then verify the HTML, XHTML, and CSS with the help of validators.
