Launching CSS HTML Validator and Validating Documents
- To launch CSS HTML Validator, press the Windows key and type "CSS". The program should appear as one of the options and you can select it to run it.
- To validate a local document, open the document using File > Open or the Ctrl+O shortcut key.
- To validate a URL, open the URL using File > Open from the Web or the Shift+Ctrl+O shortcut key.
- Press F6 to validate the current document. The validation results should appear in the Message Window.
Reviewing the Validation Messages
- After validating (like with F6), the validation messages appear in the Results Window.
- Click or double-click on a validator message to be taken to the location of the document that generated that message (if available).
- Some errors and warnings may be contained in other tabs. Review the messages in the various tabs (like Grouped, Accessibility, Styles).
- The Line tab will show the messages for the line that the cursor is on. For example, if you see that line 26 is highlighted and want to see the messages for that line, then select the Line tab and then place the cursor on line 26.
- Review the Links tab to see the links in the document and to check the links.
- When you click on a validator message, the full text of the message is displayed in the Message Window. If this window is not visible, then select View > Windows > Message.
Customizing the Validation Messages
- Right-click on the messages to bring up a context menu that allows you to disable the message or change its type (like from an error to a warning or from a warning to an error).

- These customization features allow you to customize the validation messages for your own needs, showing the messages that you want and not showing those that you don't want.
