Hi Jessica. Thanks for the link.
Here’s a video I made for you demonstrating your issue (white text color on white background color): http://cl.ly/2X26282F0K0D
And here’s some CSS that can undo that white-on-white:
/* Community Events Submit Button */
#tribe-community-events.form .tribe-events-community-footer input[type=submit] {
color: #fff;
background-color: #3578b5; /* blue color from site header area */
}
You can add custom CSS code via your child theme’s style.css file or via a plugin like Simple Custom CSS or, my favorite, Jetpack. Jetpack supports regular CSS and the LESS and Sass pre-processors.
If you’re not a CSS expert, Jetpack’s Custom Design reference may prove helpful.
Please let me know how it goes for you.
