+        <h3>Window Display Effects</h3>
         <p>
+          CEA-708 defines a couple of animation effects for when a Window becomes visible/invisible. These effects don't map into WebVTT. It may be possible to eventually provide fade in/out and wipe in/out through CSS but not at this time.
+        </p>
+
+
+        <h3>Window Colors and Borders</h3>
+        <p>
+          CEA-708 defines different colors, opacity, borders, and border effects for Caption Windows. Some of these effects can be provided through CSS. Flashing backgrounds and drop-shadows are not supported.
+        </p>

+        <h3>64 colors in use by CEA-708</h3>
+        <p>
+          CEA-708 defines 64 colors based on 4 values of each of R,G and B components. This means we can map a CEA-708 color to a CSS by using on 0, 85, 170 and 255 as values in the three components:
+        </p>
+        <pre>
+css-color(r,g,b) = cea708-color(r*85,g*85,b*85)
+        </pre>
+
+        <p>
+          CEA-708 also defines 8 named colors: black, white, red, green, blue, yellow, magenta, cyan. They map to CSS colors of the same name.
