I have some text on a document, custom formatted. I want to save this formatting as a style or a style set (I can't tell what the difference is) so I can apply it to a new page before I start typing, or to a previously created text document. I don't know if I've saved as a style correctly, because in the style gallery none of the thumbnail previews have names and they are too small to discern what fonts they use. When I open a text document that I want to change to the new style, I go to the style gallery and run the cursor over the pre-made styles (not knowing if the one I don't know whether I've saved or not, is there or not), but only the spacing changes on the document text, not the font, even when I click to apply.

I watched videos where people move the cursor over the style under the Home tab and the font of their document changes according to the style they have selected. Why does this not happen under the Design tab?

Also, why are the styles split between two different tabs, the Home and Design? Or are the ones under the Home tab styles and the ones under the Design tab style sets, and if so, do they function differently.

I am quite confused. Can anyone guide me in achieving what I thought would be a simple task.

Basically, I am writing my first novel, have set up the first chapter to my desired formatting, and wish to retain this as a style for use throughout the rest of the book, without having to set up each chapter anew.

Windows 7, Word 2016.

Thank you.
