1. Definition of Theme Library
The Theme can be regarded as the "Skin" of a presentation. It is great for improving presentation efficiency and building presentation standardization. By using a presentation theme, users can save lots of time in formatting slides and form a unified specification.
Each theme in iSlide Theme Library contains the following major (most commonly used) standard settings:
The theme font is the default font of the text, which you input in the "placeholder" or "Text Box" of the presentation. For Office 2013 and previous versions, the default theme font is Song (Chinese) or Calibri (English). But for the Office 2016 and later versions, the default theme font is Arial for both Chinese and English text.
But, iSlide has set other theme fonts, which are more standard and commonly used, for all the themes in iSlide Theme Library
Chinese font：Microsoft Yahei
Change theme font:
Change the theme font in [Design] > [Fonts], or apply iSlide [Uniform Font] feature to uniform all the fonts in the whole presentation slides.
Change theme font in PowerPoint: [Design] > [Fonts] > [Customize Fonts]
Change theme font by iSlide: iSlide > Standard Specifications > Uniform Font. Click to choose the font you want. "Theme Mode" means it will be applied to all the slides.
Each PowerPoint theme has its unique color scheme, fonts and effects, which form the overall look of the slides.
You can quickly change all the corresponding colors in your presentation by changing the color settings in its theme color.

Change theme color in PowerPoint: In the Slide Master view > Background > Colors > Customize Colors, you can change the theme color by a mouse click.

You can add custom layout in Slide Master, and once created, you can switch to Normal view to select and insert slide in this layout.

What is the difference between PowerPoint template and theme?
A template is a theme plus some content for a specific purpose—such as a sales presentation, a business plan, or a classroom lesson.
So a template has design elements that work together (colors, fonts, backgrounds, effects) and boilerplate content that you augment to tell your story.
A theme is a predefined set of colors, fonts, and visual effects that you apply to your slides for a unified, professional look.
Using a theme gives your presentation a harmonious appearance with minimal effort. For example:
When you add graphics (tables, shapes, and so on) to your slides, PowerPoint applies theme colors that are compatible with other slide elements.
Dark-colored text is shown on a light background (and vice versa), so that contrast is strong for ease of reading.
