+            <question>
+                There are many errors reported by the DefaultCssErrorHandler inside my log output. Can I ignore/disable these messages?
+            </question>
+            <answer>
+                <p>
+                    This is because our CSS parser detects some problem with one of the css resources your page relies on.
+                    Usually you will see similar error messages if you open your browser debug output window and enable the css log
+                    message.
+                </p>
+                <p>
+                    At least if you are scraping web pages you can ignore this. To suppress the output use the SilentCssErrorHandler
+                    or implement your own CSSErrorHandler.
