Spoiler/read more option in Blogspot

[CultureRevolution]

So my sister has her buiseness in a blogspot format and she wants there to be a feature where you press a phrase or a word and more text opens. Like a spoiler would on here, but obviously with other words. She asked me to help her but I don't know how to set up that feature.
Any help would be great.

I don't know anything about any of that, but you will note that there is no spoiler tag on this forum, it is missing and I really want it.

and now...
[spoiler]We do have a spoiler tag[/spoiler]

Damn, I guess I will try google again. Also the spoiler is a very good thing to have, especially when I havent seen new futuramas.
