How can I make fonts render consistently in Webflow preview and browser compared to my design in Figma/Sketch using custom CSS code?

To ensure consistent font rendering in Webflow, both in the designer preview and in browsers, compared to your design in Figma or Sketch, you can follow these steps:

1. Select a web-safe or Google Font: First, choose a font that is available on most operating systems and browsers for consistent rendering across platforms. Alternatively, you can use a Google Font, which also offers broad compatibility.

2. Import custom fonts: If you have a specific custom font you want to use, you can import it into Webflow. Go to your Project Settings, click on the "Fonts" tab, and upload the font files (usually in .woff or .woff2 format). Webflow will generate CSS code with `@font-face` rules.

3. Define font stacks: Font stacks provide backup options if the preferred font is not available. Specify fallback fonts in the CSS code using `font-family` property. For example:

```css
font-family: 'MyCustomFont', Arial, sans-serif;
```

Here, if 'MyCustomFont' is not available, the browser will attempt to load Arial and then a generic "sans-serif" font as a last resort.

4. Fine-tune font properties: Ensure that the font weight and style are consistent across Figma/Sketch and Webflow. Use the font-weight and font-style properties in CSS to achieve the desired appearance. Check the font properties set in your design tool and replicate them in Webflow.

5. Account for font loading: Fonts might load asynchronously, and the content could shift when the font finally loads. You can prevent this "FOIT" (Flash of Invisible Text) or "FOUT" (Flash of Unstyled Text) by applying "font-display: swap;" to the `@font-face` rule. This ensures that the fallback font is displayed until the custom font is loaded.

6. Test in multiple browsers: Lastly, test your website in different browsers to verify consistent font rendering across various platforms. Chrome, Firefox, Safari, and Edge are the most commonly used browsers, so make sure your fonts appear as intended in each of them.

By following these steps, you can optimize your fonts for consistency between your designs in Figma/Sketch and your Webflow website across different screens and browsers.
