I want a certain line of text to have strikethrough, as in I finished something off a list of things to do and I want to cross it off. What do I put in front of the sentence to do that? Thanks in advance.

You can use use <s> or <strike>, but the best way is to use <span style="text-decoration: line-through">.

thank you, thank you

You're quite welcome. Glad to help. :)

Actually, the best way is <del>text</del> :D

http://www.w3schools.com/tags/default.asp Both <s> and <strike> are deprecated, and using the span will make browser who do not support CSS ignore the addition completely.

Aaaaactually... the "best" way would be to use a combination of the two...
del {
text-decoration:line-through;
}
<del>This text is stricken through.</del>
...as one should rely on HTML strictly for semantical markup while styling should be delegated to CSS. ;)

the text isn't stricken through..

It is if you use it properly. ;)

And MJ, I'll happily argue semantics with you until the proverbial cows come home, but please try to stop making posts which don't contribute to a question's answer. For facetious posts we have the chat and fiction sections; let's try to keep this section as helpful as possible.
