CSS shows not available styles in the CSS style sheet.

The short answer is, no, if they are not in your stylesheet but still appear, then they are required behind the scenes for something.

More detail:

(none) - removes the class from the selected paragraph level element (heading, p).

Normal - this is your html p tag (body text). you should give this the style that you want most of your paragraph text to have. This way you don't need to apply a class to every paragraph, which is messy and not best practice.

breadcrumbs - this is a special RH style for the breadcrumbs which are added by the breadcrumbs placeholder, if you use it.

Glossary Text - this is the style used for the text displayed when you click a glossary hyperlink, if using

Default paragraph font - this one is a bit weird. It's a character class rather than a paragraph style so I think it applies to the span tag. So perhaps it's poorly named, perhaps as a legacy from when Robohelp was based on Word (about a million years ago).

The .Heading1 style in your stylesheet is not a heading style. It's a generic class selector that can be applied to any html tag you want. I doubt you'll be able to get rid of the proper h1-h3 styles as they are needed for properly structuring web content.

I personally would recommend changing the heading classes to proper tags so you can structure your content properly.

Instead of this:

.Heading1{
    font-family: "Open Sans";
    font-size: 280%;
    font-weight: bold;
	color: #0097BA;
}

Use this (don't worry, this will show up as "Heading 1" when selecting from your style list):

h1 {
    font-family: "Open Sans";
    font-size: 280%;
    font-weight: bold;
	color: #0097BA;
}

If you have already started using your styles you may need to go through and change your headings to the proper html tag. You can do this easily using shortcut keys. 

Ctrl+Alt+1 for Heading 1/h1

Ctrl+Alt+2 for Heading 2/h2

Ctrl+Alt+3 for Heading 3/h3.

(And Ctrl+Shift+n for normal/p)

*Edit to change "will" to "may", as what needs to happen depends on which html element the heading classes have been applied to

I don't think it should show there but is there a master page linked to the topics.

Look in the code of a topic. Do you see a second CSS specified or an inline CSS?

There can only be one version of any style so if you are seeing multiple versions of heading styles, what you are really seeing is one H1 style and then a paragraph style named Heading 1.

Look in the code view to see which is the real H1, it will show as

h1 {
your definitions
}

The other one will start something like p.Heading1.

You need the H1 etc as your CSS must have the heading styles. Copy the definitions across if need be.
