Spoiler tag
From Bibliotheca Anonoma
Definition[edit]
A spoiler tag is markup that conceals text or images until a user interacts with it, preventing accidental exposure to plot details or sensitive content.
Usage[edit]
- Wrap text in [spoiler]...[/spoiler] on many imageboards.
- On 4chan, select text and press Ctrl+S or use the "Spoiler" checkbox when uploading images.
Implementation[edit]
Spoiler tags typically apply CSS that sets the foreground and background to the same color, revealing the content on hover or click.
