A theme is a preset group of colors, fonts, background, and layouts to make your presentation more visually appealing. Google Slides has a number of built-in themes.
Copying the practice presentation
If you are beginning this course at this point, you will need to copy the presentation to your Google Drive.
NOTE: If you have been working through the course, your file should be up to date and you will not need to copy the practice presentation. You can move ahead to Applying a theme.
- To begin copying the practice presentation in a new browser window,
Right-click Copy practice presentation, Click Open link in new window
The file begins to open in a new window of the web browser. Before the presentation will open and can be edited, we need to make a copy of it.
Move to the new browser window.
- To copy the presentation file, in the browser window,
Click 
A copy of the file is now open and, by default, is saved in your Google Drive. The filename now has the words "Copy of" at the beginning.
