Hello, I'm building a site with the Third Layout theme and our CEO wishes for the text of the navigation menu at the top of the page to be increased in size from 12 to 16. That change I have been able to make without an issue. However, when shrinking the dimensions of the web browser, the menu no longer properly collapses. The navigation buttons will overlap with the company logo and double stack before transforming into the drop-down navigation button like it should. Can you tell me what code I should be looking for that controls at what width the menu transforms into the drop-down button?

Thank you.
