problem with custom style tag

(added) I think I see the error in your syntax: you must call the new style after you create it. See the (new) last line of code in the sample I provided.

This assumes that you really have defined a class called "my_style" that you use on hyperlinks, and that "my_style" would not be overridden by an "a" tag class further along downstream in any CSS inline or CSS file attached or linked.

{edit}(added) When using this feature in the CKEditor, you must first select a hyperlink, then click on the Styles menu. If you do not select a hyperlink first, you will not see the styles bound to the 'a' tag.

{edit}(deleted some incorrect info)

You either need to define the individual attributes of the a tag right there in your code, or else if you are calling that class, you have to let the editor know where to find the class. Maybe something like:

<textarea name="editor1"></textarea>
         <script type="text/javascript">
            CKEDITOR.replace( 'editor1' );
            CKEDITOR.add
            CKEDITOR.config.contentsCss = '/MyCSSFolder/MyCSSfileWithTheMy_StyleClass.css' ;
            CKEDITOR.addStylesSet( 'custom',
            [
            /* Block Styles */
            { name : 'Blue Title', element : 'h2', styles : { 'color' : 'Blue' } },
            { name : 'Red Title' , element : 'h3', styles : { 'color' : 'Red' } },
            /* Object Styles */
            { name : 'Custom a', element : 'a', attributes : { 'class' : 'my_style' } }
            ]);
            //{edit} (added the next line, calling the "custom" styleset 
            CKEDITOR.config.stylesCombo_stylesSet = 'custom';
         </script>

(added last -critical- line of code in the above sample) You must call the stylesCombo_stylesSet, not just create it.

I am also wary of using any word in coding that might be a reserved word, so I would use a different word than "custom" to define this styleset. (I would also use a better description name for a class that modifies attributes of the "a" tag, like maybe "linkBigGreen" or something like that, rather than "my_style" - and I code that way whether someone else has to read my code or if it is just me.)

p.s. I took the time to go through a number of things regarding the Styles combo items, and this may be of further help: viewtopic.php?f=11&t=16349

My previous post was not a good answer, and had bad guesses and errors. I have edited the living crap out of it, and it should be more useful now.
