How can you make your web application accessible to users with different font preferences?

3 Use web fonts wisely

Web fonts can be a great way to enhance the appearance and branding of your web application, but they can also present some challenges for accessibility. For instance, web fonts can take longer to load, which can negatively affect performance and usability. Additionally, web fonts can override the user's font preferences, making text harder to read or understand. To make the most of web fonts, it is important to follow some best practices. These include using web fonts sparingly and only for headings or decorative elements, not body text; providing fallback fonts that are similar to the web fonts in case they fail to load or are blocked by the user; utilizing the @font-face rule to specify the web fonts and their sources, formats, and styles; and using the font-display property to control how the web fonts are displayed while loading (e.g., swap, fallback, or optional).

4 Test and validate

Finally, to make sure that your web application is accessible to users with different font preferences, you should test and validate it with various tools and methods. For example, you can use browser tools, such as Chrome DevTools or Firefox Developer Tools, to inspect and modify the font properties and see how they affect the layout and design of your web application. You can also use accessibility tools, such as WebAIM or WAVE, to check and evaluate the font accessibility and compliance of your web application. Moreover, you can use user testing and feedback to understand and address the font preferences and needs of your target audience.
