Caps

All capital letters can be used for a specific EMPHASIS in explaining. (BE CAREFUL THAT ALL CAPS AREN'T USED FOR THE ENTIRE PARAGRAPH, OR IT WILL COME ACROSS AS SHOUTING AND/OR LAZINESS TO PUNCTUATE RIGHT.)
 

Bold

Bold-emphasis works good for titles like above, Showing Literary Emotion with Punctuation.
 

Size

Altering the size of text will also add emphasis for a headline to be seen. This sentence you're reading right here is 10 point size. The next sentence in the middle is 24 point size:

How to show emotion through writing!

...or even small enough to be felt as a whisper, like a secret (at 8 points).
 

Italics

Italics are used to draw attention to a particular part of text, used on titles of books, poems, newspapers, magazines, movies, plays, songs, names, or to tell a caption of someone's words, like below. By the way, here is a type/font sizing secret you can use on many web pages you might come across:

"Ever notice some words are too small to read on some internet pages? You can resize the type on a webpage most of the time to either enlarge it to where you can read it, or shrink words down smaller to where you can get a better perspective, by holding down the Control key (PC) on the keyboard, or Command key (Mac), & scroll your mouse at the same time. This will instantly resize the page to however you need it to look.
 

Font

The style, shape, or design of letters, shows the face of what is said, like observing what a person's exterior, or physical body looks like.

The Emotion font's name above is "Bradley Hand ITC". Difference font styles convey different emotions. At FontGarden.com where you can view other people's handwritings, or also turn your own handwriting into a font or even make money if you agree to sell your font.

However, not all people's browsers support your particular font other than the standard ones that come with your computer, resulting in whatever font showing up that the computer replaces it with, if using online; but can be good for letter writing to then print.
 

Content

What you actually say when you write, is the underlying person that speaks. Toccara, a contestant on the 2004 America's Next Top Model TV show says with a smile:

" I'm 180 pounds, I'm gonna be America's first black, plus-size model, and I'm fabulous!! "    
("Christine" font style)


You can make your inner radiance shine confidently through content.

 

Punctuation

Exclamations, tells a personality. Although, used altogether in the other extreme, comes across as  @#&*!! cursing. Using a curse word every other sentence, has the same distaste as mentioning a religious deity in your speech just as often, and also the Valley Girl  way speech: "Like, I mean, for like sure, this is like totally cool !!"  Exclamations are best used sparingly and to make a point.
 

Highlighting

Highlighting is used to draw quick attention in long periods of text to catch the readers' eye, used mostly on sites that give a long "sales pitch" before their product to get you to buy, where there's so much mesmerizing information, they have to find a way to make their content simple, and often highlighting the main points is done.
 

Underline

Underlining can be found in writing of book titles, used as more emphasis, or in hyperlinks. There is truly a way to communicate through written form with all this written form of expression available.
