>> Jen Kramer: All right. With that in mind, how we just did that, that's how we coded that exception to the rule. I want you to take a minute, and I want you to think about the last row. So, what's the difference between the last row and the one above it?

[00:00:15]
Yeah?
>> Speaker 2: It's triple the size of those.
>> Jen Kramer: We have one button that's triple the size. Correct? Go on ahead and try coding that row, now. Fabulous. So, hopefully you came up with a solution kinda similar to mine. So, I have, in my row, I have a button here.

[00:00:32]
It's just 0, and I added a class called triple. Since I added one called double, before, we'll call this one triple. Okay? And then, my other button says =. Right? So, now, if we take a look at this in the web browser, that's how it's looking now. Hey, it's kind of vaguely, sort of, calculatory.

[00:00:54]
Isn't it?

>> Dave: Is there any disadvantage to have just used the equals button on my keyboard or, instead of the-

[00:01:31]
Yeah. Sometimes there can be processing errors or whatever. Yeah. So this is just, generally, the better way of doing things. So, now, let's go through, and let's start putting in some CSS.
