I was wondering when reading an article posted by Miaw, si KucingTengil about the crop circles. She put a spoiler button on the article to open some images in order to save place. Then I immediately did some research on how to add the spoiler button. I found some tutorials but most of them were too complicated. We have to put the javascript to our template's HTML script. After collected some script resources and tinkering Miaw's blog scripts, I started learning the script and tried to modify it. And violaa...Here is the easiest way to add spoiler to your blog post. I'm gonna show you how with a spoiler button.
Just put below codes on your post. But remember to edit your post on Edit HTML insted of Compose.
