Multi font refers to the use of multiple fonts in a design or layout. This can be done for various reasons, such as creating hierarchy and emphasis, adding visual interest, or improving readability. Using multiple fonts can be a great way to create a unique and cohesive design, but it can also be challenging to balance and harmonize the different fonts. When done correctly, however, multi-font designs can be visually striking and effective. There are many design principles and guidelines to consider when using multiple fonts, such as selecting fonts that complement each other and using them consistently throughout the design.
