My site templates support content/trigger warnings. I took inspiration for this from Mastodon, as it’s one of the better features of that platform. It gives people the chance to opt out of reading content that might be objectionable to them, or which they don’t want to accidentally appear on-screen at a workplace or the like. Or for people who do want to read it, it gives them a chance to center themselves and prepare for what might be coming.
I do this because I have a history of trauma. Certain things, when seen without warning, have a tendency to hurt me badly. But being warned about the content allows me to prepare for it, and if I know what I’m getting into I know, from my own personal experience, that I can face it without having a panic attack.
