All content on a web page is rendered with HTML, so we can use HTML tags to handle basic text formatting. ** Notice that these tags work like parentheses — your content goes inside them. Also notice that the closing tag is identical to the opening tag, EXCEPT there is a “/” at the beginning of the word or letter.

Bold

If you’d like to make part of your text bold, simply do this:
<strong>This text is bold</strong>

And you get this: This text is bold

Italicize

If you’d like to italicize something, simply do this:
<em>This text is italicized</em>

And you get this: This text is italicized (** the “em” stands for “emphasis”)

Strike Through

Sometimes, when you’re writing a sentence, it’s fun to give the impression that you started to write one word, but then chose another. You can accomplish that in this way:
Ah, what an <del>insipid</del> insightful comment!

And you get this: Ah, what an insipid insightful comment!

Quote

If you want to insert a famous quote, or just quote something that was said in a previous comment, do this:
<blockquote>Four score and seven years ago...</blockquote>

And you get this:

Four score and seven years ago…

Links

If you’d like to insert a link to another page, you can do that too by using an “anchor” tag. But be careful — too many links and WordPress will think your comment is spam.
<a href="http://google.com">Google</a>

And you get this: Google

Just remember to always put in your closing tag, or things will start to look really funky! Hope this helps — happy commenting!

Tip: When I’m writing HTML, I often find it useful to go ahead and type in the closing tag right after I’ve typed in the opening tag. Then I go back and put whatever content I need in between them. I’ve found that cuts down tremendously on the number of mistakes I would otherwise make.
