Just to put some imputs more .....

 

I'm defining an style like this

<style>
.headline {
           color:#066A84;
           font-size:18px;
           font-weight:bold;
}

</style>
The classes are now shown in a drop down (f.e. headline) so a User can select and change the style of selected expressions like this .......

<DIV class="headline">Dato por Ver</DIV>


So to see the results on the screen I'll need to put <style>
 into the editor


Many Thanks,
AAP
