I looked at your website pages and found that this is not just an issue with your pages with tickets. Your website theme Unicon actually struggles to adapt to mobile sizes on some of your other pages.
I can give you some CSS to help your Event Espresso pages.
@media only screen and (max-width: 768px) {
.single-espresso_events .container .twelve.alt.sidebar-right {
width: inherit;
max-width: 100%;
font-size: medium; }
}
Steps to Implement:
1. Add this code to your WordPress site’s Additional CSS section:
– Go to Appearance > Customize > Additional CSS in the WordPress dashboard.
– Paste the code
– Save the changes
2. Save and test the behavior on a mobile device or by resizing your browser window.
