Why isn't the menu working?

Well. Who knows? Anyway, I ran into the problem that the menu didn’t work at all in my mobile phone’s browser. I (then) had a Samsung phone with a very old Android version, but what that means for the built-in (?) browser I don’t know. Luckily, the Chrome browser (developed by Google) was installed on the phone when I bought it, and in Chrome everything works exactly as intended.

So my advice to you is:
Use another browser. Browsers for your phone, like Google Chrome or Firefox, can be downloaded (free of course) and installed on your Android device from the Play Store. For Apple products, the download service is called the App Store, with the caveat that the link might possibly point somewhere incorrect for you. What the download service is called on other devices I don’t currently know, but it shouldn’t be too hard for you to figure out or look up.

In addition, there is always a link to the homepage (home) at the very top of all my pages (click on the site’s name (SethP’s)), so you can always reach this information from there.
