For a Document (Word-like) in Google Docs, I want to be able to change the font size, family and spacings for the built-in in styles. How can I do that?
This can be done in new Google Docs (Drive) as well.
- Do the necessary styling in a part of the document.
- Place your mouse pointer over this location.
- Click on the style selector and select the style you want to change the defaults of.
- Click on update option to change the defaults.
This ability has been removed from the new version of Google Docs. As of now, you're able to tell Google to use the old version, but this comes with trade-offs, and only affects new documents.
In the Editing tab of your settings, see the following option:
Here are some of the most interesting features of the new version of Google documents:
- Real time collaboration: See updates from other collaborators as they edit the document.
- Higher-quality imports: More consistent imports from your desktop into Google Docs.
- Chat with other collaborators: As you make your edits, you can chat with other document editors about the changes, from within the document.
- Ruler: Google documents have a ruler for setting margins, indentations, and tab stops.
What else is different?
You'll probably notice that some features from the older version of Google documents aren't available yet. Don't worry: we'll be adding a lot of them soon.
These features from the previous version of Google documents, however, won't be available in the new version:
- Offline document access via Google Gears
- Edit HTML
- Edit CSS
As @Gokul N K said, you update the normal styles to become the default styles for that document. However, if you would like to change the default styles for every new document:
- Update the styles that you want for every new document on a new document.
- Click on the styles button > options > Save as my default styles
