Ryviu uses the current theme's font for your product reviews by default. To modify the font, follow these steps:
First, go to Settings > Customer Reviews > Customize theme > Typography.
Then, you initially find the font set as 'Default' in the font settings. Ryviu offers a variety of fonts for you to choose from. Select your preferred font.
Finally, remember to click the Save button to apply the changes.
If the font you desire is unavailable in the provided options, you can still change the font of your review widget using CSS coding.
