It’s super easy to do this and easy to remember. :) Here’s a set of things you can do in the description, and I’ll post this publicly so everyone can see it. This applies to all themes:
<center> and </center>Changes text-align to centered.
<strong> and </strong> or <b> and </b>Changes the text to bold weight.
<em> and </em> or <i> and </i>Italicizes the text.
<u> and </u>Underlines the text.
<big> and </big>Increases the font size.
<small> and </small>Decreases the font size.
Here are a few more that are a little harder to do, but they’re fun to play with if you want to change things up a bit. For these, you can change the values in order to create the effect you desire (for example, change “1px” to “4px” or change “#FF0000” to any other color code):
<a href=”http://www.LINKHERE.com/”> and </a>Inserts a link into the description.
<div style=”text-align:left;”> and </div>Changes text-align to left (you can replace “left” with “right”, “center”, or “justify”).
<span style=”letter-spacing:1px;”> and </span>Increases the space between letters.
<span style=”font-color:#FF0000;”> and </span>Allows you to change the font color of the text.
<span style=”font-size:14px;”> and </span>Allows you to change the font size to any value.
Just copy and paste the code, and it’ll work! :)
