HTML Purifier filter I installed HTML purifier because the default input format is filtered HTML and my users need to be able to add inline styles to the elements in their nodes. I'm trying to get it to work, but it is not very intuitive and there doesn't seem to be much documentation out there. 

Can someone please suggest a tutorial or tell me how I can add the style attribute as well as width and height?
What wysiwyg editor are you using? In my end I'm using TinyMCE and I have a related task as yours. What I did was I created a plugin to insert a class on a selected texts. Doing this will provide a convenient way to your users to add styles. 

Note: you can use hook_wysywyg_plugin() for this.

Hope this help!
