1. Description

The Off-line CSS Validator clipbook gives NoteTab users a convenient and easy-to-use interface to an offline version of the W3C CSS Validator. This allows very efficient off-line validation of CSS style sheets (without the Internet connection), and the level of rigor is the same as that of the current (March 2006) W3C CSS Validator. Note that this is real validation.

This clipbook consists of three groups of macros:

Besides this, a corresponding clipbar with a set of toolbar icons is provided for use in NoteTab Pro and NoteTab Standard.

2. Download and install

  1. Download the self-extracting archive offline-css-validator.exe. It contains the clipbook and the CSS validator binaries.
  2. Run it and extract the archive to the NoteTab program directory (typically something like "C:\Program Files\NoteTab Pro" or "C:\Program Files\NoteTab Light")

Installing Off-line Validator clipbook and clipbar to the NoteTab Pro program directory

The clipbook, the clipbar, and clipbar icons will be added to the NoteTab "Libraries" subdirectory, and the subdirectory called "css_validator" will be created. The "css_validator" subdirectory contains validator binaries and the required accompanying files.

NOTE: You may need to download and install Java 1.4 or higher to be able to run the Off-line CSS Validator.

3. Usage

To use the clipbook, select "CSS Validator" in the clipbook list. In NoteTab Pro/Std you can also enable the clipbar (menu View-Clipbar-CSS Validator).

Off-line Validator clipbook and clipbar in NoteTab Pro

Open a CSS document which you like to validate. To perform validation, for example, against CSS2, run "CSS2" macro either from the clipbook window or from the the clipbar.

If there are errors and/or warnings, they will be shown in a separate document window.

List of detected errors

To jump to the position where the first error in the document was detected, run "First ERROR" macro. You will be taken there, and the description of this particular error will be shown in a message box. If appropriate, the corresponding tag will be highlighted. (Note: the line number in the message box is actually the paragraph number; if line wrap is off, the line number is equal to the paragraph number.)

Jumping to the first error

To browse through the errors, you can use "Next ERROR" and "Previous ERROR". However, it can be recommended to correct the first detected error, and then run validation again.

To browse through the warningss, you can use "First WARNING", "Next WARNING", and "Previous WARNING". Again, it can be recommended to correct the first detected warning, and then run validation again.

NOTE: Currently, this Off-line CSS Validator validates the disc files, and not on what you see (unsaved yet) on the screen. Don't forget to save the edited file before running the CSS Validator again.

If there are no errors, the corresponding message will appear.

Congratulations if no errors

Tip: In addition to this Offline CSS Validator, download and install my Offline HTML Validator, and enable a combined clipbar (menu View - Clipbar - HTML+CSS Validator). Then you will have both tools in one toolbar:

Combined HTML + CSS Validator clipbar

Both tools can be downloaded and installed in one package: Offline HTML+CSS Validator (offline-html-css-validator.exe).
