Color: ppt design should generally not exceed three colors (the so-called three-color principle). Too many colors will look messy and fancy. It doesn't have to be like this. For example, some brightly colored designs are brightly colored, and they will not be ugly if there are many colors. In a word, color matching is unified and coordinated.
Picture: the picture is concise and clear, and the definition is better. Usually do design, and collect good pictures when browsing the web. Over time, I have my own picture material library.
Font: ppt must first ensure that the following audience can see it clearly, so it is recommended to use "sans serif font" in general design ppt, which will look more neat. You can also download beautiful fonts from the font website.
Typesetting: All design typography principles are similar. Four principles of design in typesetting:
Intimacy-those contents should be put together and those should be separated. In perfect order
Alignment-as the name implies. Simple alignment can make the design neat.
Duplicate-The same content (such as items, items, lists) is designed in the same or similar format. Let the design have a sense of integrity.
Contrast-as the name implies, it is contrast and emphasis. Can highlight the key points of design.
Note: When using special fonts not included in the system in ppt, pay attention to embedding fonts when playing on the computer: file-options-save-embed fonts.
Many people like to put animated pictures in gif format in ppt. It is suggested to use it as little as possible in more formal occasions, which will be counterproductive.
