Troubleshooting Contact Form 7 Submit Button Style Issues

Hey Andrew, let's break down why your Contact Form 7 submit button styles aren't matching what you expected—this is a super common problem, so let's walk through the most likely causes and fixes:

CSS Specificity Conflicts
Your current selector .wpcf7 input[type="submit"] might be getting overridden by more specific styles from your theme or other plugins. For example, if your theme uses a selector like .site-content .wpcf7-form input[type="submit"] or adds !important to its own button styles, your code won’t take precedence. To fix this, try making your selector more specific—like body .wpcf7 input[type="submit"] or even .wpcf7-form-control.wpcf7-submit (since Contact Form 7 adds that class to submit buttons by default). Avoid overusing !important unless absolutely necessary, as it can create future styling headaches.
Caching Problems
Don’t overlook this simple fix! Browsers and WordPress caching plugins (like WP Rocket, W3 Total Cache) often hold onto old CSS files, meaning your new styles aren’t actually being loaded. Clear your browser cache (use Ctrl+Shift+R on most desktop browsers for a hard refresh) and flush any server-side caching on your site. This ensures your updated Additional CSS is pulled in properly.
Incorrect Selector Target
Take a quick look at the button’s actual HTML using your browser’s dev tools (right-click the submit button > Inspect). Sometimes Contact Form 7 renders submit buttons as <button> elements instead of <input type="submit">—if that’s the case, your current selector won’t match anything. Switch to targeting the button’s dedicated class directly with .wpcf7-submit instead; this works no matter if the element is an input or button.
Syntax or Typo Errors
While your code looks correct at first glance, even a tiny mistake (like a missing semicolon, unclosed curly brace, or extra space) can break your CSS. Double-check the "Additional CSS" section in your WordPress Customizer to make sure there are no syntax errors before or after your button styles that might be causing the code to fail.
