Life in HTML

I'm learning to make HTML documents. It's been pretty easy so far. Tag this and use an argument in that.
That's what they're called, arguments. Kind of like math where everywhere you see problems. Probably why I'm an English major.
Either way, now I'm learning to make something called cascading style sheets. These sheets are a basic style that you can apply to all your webpages. They can specify font, font color, background color, size of the font, and have lots of other uses. I could have a style sheet for life. To have just one style: Me. And to apply that to my life. The organization of my life is probably better than the organization of my scattered room in that I'm starting to know what I like. I like to write. I like to knitt. I'm getting rid of my debt, and working at Chunk E. Cheeses.
I did spend some money today on my a couple of balls of yarn and a strap for this brown purse I made. My mom dragged me to the craft stores and I couldn't help myself. That's 6.69$ away from paying my first debt. However, yesterday I finished 15 articles bringing me to 37.50$, minus whatever paypal takes away in the transaction. The woman I've been working for wants an invoice. Why does she need an invoice? What is an invoice?
Invoices are, in reality, bills. Talia, who I'm working for, said the buyer of my work has started getting iffy about the payment. I suppose she wants me to send the bill to the buyer. Well, I'll see what I can do about the invoice. Better learn about these invoices if I'm going to be a freelance writer, now rather than later.
