While in WYSIWYG environment user have no concept of the CSS (and the DOM either). You have just something like <code><combobox id="list-of-fonts">...</combobox></code> in the UI. I am trying to eliminate the need of inline styles in <code><richtext></code> input element (WYSIWYG editor) though. Inline styles are needed for WYSIWYG editors.

I typed < and > in the post above literally and thus no example has appeared. Ok maybe "BlackNote+WordPress" should transform them into escaped form automagically, maybe not. In any case the example is: <div style='hove:color:red;link:color:ggreen;' ></div> Dusan Ah? I typed < and > in the post above literally and thus no example has appeared.

Made me think of the following. What makes applying CSS to DOM , *much* more complicated is (optional) existence of the 'style' attribute. Conceptually I think I see no reason of its existence? It makes the whole CSS + DOM (already complex) rules issue NON cocnsistent and introduces singulartities which is bad. Or should I say BAD. Also. It is not possible to use selectors inside the style attribute value. Why should we have this, one might ask? First I can think of, is unability to use pseudo class in the value of style. Example : <pre><div style=’hover:color:red;link:color:green;’ ></div></pre> Of course this does not work. Selectors inside style values are not permited. Of course, why in the first place anyone would use the 'style' attr, I can not comprehend. It is much more clear and easier to develop and manage CSS through element and selectors, classes and id's.
