 And in today's GUI Challenge, we're building a switch group, and that's not a button group. This looks like a button group, but if it's a button group, each of these could be highlighted in blue. But notice how, as one is enabled, it disables all the other ones. This is a switch group. Only one of these can be activated at a time. I mean, it makes sense, right? It can't be left-aligned text and right-aligned text at the same time. So I'm excited to break this down for you. I got some great HTML to show you and some cool CSS tricks. Let's get started.
