I have a website that was designed in Dreamweaver with a css style sheet that lives in a css folder. I am turning over site's content editing to someone using CC HTML editor. The content person will be using the visual editor tab since she does not know html code. However I cannot see how to customize the settings so that the styles on the style sheet are available in the visual editor. So far anything she edits shows up with all these extra font tags and is messing up the code. I would like to teach her to apply the styles the site was designed with and keep the code clean.

Hiya George,

I wouldn't suggest that you do the Visual Editor at all unless that is the only way they will be doing it. The Visual and Code sides of the program do not play nice together. If the person taking the site over intends to use only the Visual side, please be sure they are aware that you CANNOT swap back and forth between the 2 different editor styles as it will mess up the code to the point of unusability.

My guess is that the extra tags and such are caused by this anomaly with the program. I do hope they kept a backup of the original files to start from there again.

I have helped a few total newbies to work with the HTML Editor in code mode without their knowing a word of code.
The easiest thing to do is to go into preferences and change the colour options so that everything but the actual default text shows up in a very pale grey. Just leave comments in a strong colour, and the default text in another one.
That way my clients have known to just look for the text to change, and the comments to understand what areas of the page they are changing.
Hope that is clearly put...
But it certainly means that you can avoid the situation Jo Ann describes with the incompatible visual and code editors.
It will just take you a little longer to explain to your client how to effect changes, but it will be worth it in the end to avoid the site breaking apart and messing up your hard work!

ps...remember to leave a good amount of useful comments scattered throughout the code so that your client can better understand what refers to what.

I would never have let someone who is not able to code mess with a website that has a css, and in a programme that uses absolute positioning.

I think Janys's suggestion is the best I've come across for a situation like this.
