The Playground

I don't know what you use to enter your posts, but on my entry screen there is no button for strikethrough.

Don't depair: there's an easy way to overcome this with a simple text decoration style.

A line of text using strikethrough called line-through.

<p style="text-decoration: line-through;">A line of text using strikethrough 
called line-through.</p>

How about a line above your text for something different. It's the opposite of underline: overline.

A line of text with the line above called overline.

<p style="text-decoration: overline;">A line of text with the line above  
called overline.</p>

Blinking text is something I never think to use, and it is so easy. To really grab someone's attention, this text decoration is a winner.

These styles are easy to remember because they are named by what they do. Remember: blink, overline, underline, and line-through.

Blinking text is really quite annoying so I wouldn't recommend using this one too often.

Another way to make your text stand out would be to use the Font Variant style, Small Caps.
