Please test this spoiler hide-show system in your mobile device. The hidden spoiler text in the box below will only appear if you click the "show spoiler" link, assuming this works.

This is the hidden spoiler text, if you can see this without clicking the "show spoiler" link before this, then this has failed.

If you can't see the spoiler sentence above, part 1 has worked. If you can see the spoiler text AFTER you clicked the link, then part 2 has worked. Thanks!
