Heading text tags are traditionally the first to be taught to budding new programmers. And who am I to deviate from tradition?
       Heading text tags follow the format of <hx> where the "x" stands for a number between one to six. When you employ a heading tag, the result on the webpage is text that is a given size and made bold, like so:

As you can see, <h1> is the largest heading, whilve <h6> is the smallest.

There are several very simple, very basic tags used to format text, just as if you were using a word processor. There's a tag for italic, bold, superscript and subscript, and a few others. All of these tags are super basic. There are no attributes for any of these tags, so I won't be putting that field in the "Quick Information".
      I think that these tags will be self-explanatory. The bold tag, <b> makes text look bold. The italic tag <i> makes textitalic. The underline tag <u> makes text underlined. The teletype tag <tt> makes text teletype; basically, it looks like typewriter text. The superscript tag <sup> makes text ^{superscripted}. The subscript tag <sub> makes text _subscripted.
      Although tese tags are simple, nesting becomes a slight annoyance. You can make text italic, bold, and underlined, and that's fine. But when you have to put the end tags in to stop the effect, there might be a potential non-intuitive question: "Does the order matter?" No, the order does not matter; just make sure you end the tags, or you'll get weird unexpected text! However, it is by convention that the last tag to be placed has its endtag place first. And so forth. Nesting has no effect on the text, other than the effect you want. You can nest tags til the cows come home and nothing will happen.

Sure, all those tags are fine, but what do you use to change the font from that ugly Times New Roman? If you're smart (and even if you're not), you probably figured out that you use the <font> tag.
      The <font> tag is the tag you use to change the font "face" or style (i.e., Times New Roman, Arial, Helvetica, etc., etc., etc.). You can code for more than one type of font, so that if a computer doesn't have the first choice, it will look until it finds one of your choices, like the below example:

Have you ever wanted to use a character that wasn't on your keyboard? If you own Windows 3.x or later, you would normally go to the "Character Map". Mac users go to the "Key Caps" under the Apple^© menu.
      In HTML, such characters -- ones not featured on the keyboard -- are referred to as "special characters." Common special characters you may recognize are the copyright (©), the trademark symbol (™), the degree (°), and the regular bullet (•). But since you can't type these in as easily as an "a" or a "5" or even a "?", you must use a special syntax to code these characters into your text; don't think that Dr. Berners-Lee didn't think of that.
      Right now I must digress. As you may or may not know, there are several lists of characters, such as the ASCII or ISO10646 (aka Unicode -- a character set that comes in 8, 16, or 32 bits -- the standard), and others. The special character encoding syntax uses a modified ASCII (American Standard Commerce Information Interchange), which brings the total amount of characters you can encode to 256 (including "normal" ones such as "a" "5" or "?").
      You can code special characters using the syntax below:
