How to Fix Unwanted Borders and Styling on Mobile Forms (Especially iPhone Safari)

Improve Your Website's Mobile Design and Form Consistency Without Code

When designing a professional website, especially for mobile visitors, one common issue many businesses face is the unwanted default styling applied to form fields, particularly on iPhones and in Safari browsers. This often shows up as grey borders, rounded corners, or inconsistent field backgrounds that clash with your website’s design.

If your beautifully designed site suddenly looks clunky or outdated on mobile—it’s likely due to default browser styles overriding your own. This guide will show you how to fix that issue and ensure your form fields look clean, modern, and fully on-brand across all devices.


✅ Why Do Form Fields Look Different on iPhones?

Browsers—especially Safari on iOS—apply their own built-in styles to elements like:

  • Text input fields
  • Text areas
  • Dropdown menus
  • Submit buttons

These default styles include:

  • Grey borders or drop shadows
  • Rounded corners
  • Inconsistent font sizes
  • Background colors or highlights

These are not caused by your design or platform—they’re enforced by the browser itself to maintain basic usability. However, they often conflict with your brand’s look, especially on modern mobile-responsive websites.


🎯 Why Fixing Mobile Form Styling Matters

Whether you’re running a service-based business, managing a lead generation funnel, or selling online, your form fields are conversion points. They should feel seamless and branded—not out of place.

Fixing mobile form styling helps you:

  • 🧩 Maintain visual consistency across all devices
  • 📱 Improve mobile user experience by removing clunky browser defaults
  • 🎨 Keep your branding tight with consistent colors, borders, and spacing
  • 🚀 Increase form submissions by building trust and professionalism

If your form feels off, cluttered, or outdated, people are less likely to fill it out.


🔍 How Do You Know If Your Forms Are Affected?

Here are signs your site is using default styles you didn’t intend:

  • On iPhones, input fields look grey or inset even though you set white backgrounds.
  • Buttons appear slightly 3D or rounded, different from the rest of your site.
  • Form borders don’t match the color scheme on mobile devices.
  • There’s a visible outline or shadow when tapping into a form field.

These issues are subtle—but they add up, especially on mobile where every design element matters.


🛠️ How to Fix Mobile Form Styling Issues Without Code

If you’re using a website builder like GoHighLevel, WordPress, Webflow, Wix, or Squarespace, the good news is: you don’t need to write code to fix this. Most platforms allow you to:

  1. Access a visual CSS or theme settings editor
    – Look for a “Custom CSS” section, “Form Styles,” or “Field Design”
  2. Override default field styles using pre-built settings
    – Set custom border colors, spacing, fonts, and focus styles
  3. Disable platform-specific browser styles (called “appearance settings”)
    – Some themes or plugins let you toggle off native styling for form fields
  4. Test on a real iPhone or using a responsive preview
    – Always double-check how it looks in mobile Safari or browser emulators
  5. Use a theme or funnel template built with mobile styling in mind
    – Choose one that’s already optimized for consistent design across devices

📱 How GoHighLevel Users Can Apply These Changes

If you’re building forms and landing pages inside GoHighLevel, you can:

  • Use the “Custom CSS” field inside funnel or website settings to globally adjust form styles
  • Choose form components that allow border customization within the builder
  • Test mobile views directly from the builder or on a physical iPhone to confirm changes
  • Work with a template that already includes neutral, mobile-friendly input styling

📈 The Bottom Line

Default browser styles—especially on iPhones—can undermine your brand presentation and hurt mobile conversions. Fixing this is not about "design perfection"; it’s about ensuring a professional, clean experience that builds trust and encourages action.

Whether you’re using GoHighLevel, WordPress, or another builder, make it a priority to:
