-We created a stylesheet
-We named our class "mystri" because we like the way that sounds when said aloud.
-We assigned the class "mystri" to a div tag.
Note: You could use HTML strikethrough tags if you prefer (<strike> or <s>). But both of these HTML tags are depricated in HTML 4.0.1, meaning they may become obsolete in future versions of HTML.
Example:
<strike>Hello</strike> or <s>Hello</s>
Hello Hello
Wrap the text you want to be strikethrough in HTML's <strike> or <s> tag.
