Using White font in Topic Author area

I assume your using the Dark skin for Frameless output. If you're not using that the following won't apply; post back with the skin you selected and the output you're generating.

I couldn't see a place to set the body font colour in the skin, so I assume you set it in your topic stylesheet. I don't think you need to set the body font colour in the topic stylesheet as that seems to be handled by the skin somehow. I tested this by generating Dark Frameless with a topic from which I'd removed the stylesheet, and made sure I wasn't using a master page either. The font came out white in the output, even though it was black in the editor.

If you've set the body font colour in the topic stylesheet, go back and select the square with a diagonal red line through it. That should remove the colour setting and hopefully will be readable in the editor and white in the output.

White text on a white background has always been a bit of a problem as you have to select the text to read it. 🙂

Why is applying colour to the body "a bit of a problem"?

Another way of working would be a white background and black text but then apply a master page in the output that is linked to a CSS that has your final colours. Against that though is that you will not be seeing what you end users see.

If you intend to produce printed documentation outputs, you will need to do that anyway for those outputs.

I amended RH'19 to the correct name as it helps people searching for answers. RoboHelp 2019 is in fact version 14.
