I did not get much done today, because the day was all about trying out something completely new, and above all I got up at 1:30 PM.
First I looked into the down arrow, like the one you can see on Google, for example. After a lot of testing in every browser imaginable, I figured out that it is done purely in CSS.
And I had been trying all sorts of WAI-ARIA stuff, I had already studied it, but I could not find my way around the complex code of Google Calendar, especially the minified JS. Then I looked at how to build a drop-down menu, again taking inspiration from GCalendar. In the end I managed it with jQuery UI, but even so it was a matter of trial and error.
If I had stopped to think about what I was doing and worked with my head instead of my hands, it might have gone better. In the evening, from midnight, I threw myself into the Alarm Clock app. First I created a C# solution called Budik, but I immediately realized I should name it something like Alarm if I wanted to put it on the international Windows Store. By 2 AM I had a finished GUI design, which has not changed much in the final version.
But I no longer had the energy to program it today.
