If you're facing issues with VH (viewport height) and VW (viewport width) units not functioning correctly in Safari 5.1 when using Webflow, there are a few possible workarounds you can try:
1. Use JavaScript polyfills: You can use JavaScript polyfills like "viewport-units-buggyfill" or "viewport-units-polyfill" to fix the issue. These polyfills detect browsers that don't support VH and VW units properly and provide a fallback solution using JavaScript calculations. You can include the polyfill script in your project, and it will handle the unit conversions for you.
2. Implement conditional CSS: Another workaround is to use conditional CSS targeting only Safari 5.1 and adjust the styling accordingly. You can create a CSS rule specifically for Safari 5.1 using media queries and override the VH and VW units with pixel-based fallbacks. For example:
```css
@media screen and (-webkit-min-device-pixel-ratio:0) {
/* Safari 5.1 specific CSS */
.my-element {
height: 1000px; /* Fallback height in pixels */
width: 50%; /* Fallback width in pixels */
}
}
```
This approach allows you to provide specific styling for Safari 5.1 without affecting other browsers.
3. Adjust your design: If the above workarounds don't solve the issue, you may need to rethink the design and find alternative solutions that work well in Safari 5.1. Consider using alternative layout techniques, such as using flexbox or CSS grid instead of relying heavily on VH and VW units.
It's important to note that Safari 5.1 is an outdated version, and Webflow may not provide full support for it as they prioritize modern browser compatibility. It's always recommended to encourage users to update their browsers for better compatibility with modern web technologies.
