Blogger 'spoiler tag'?

okay so on my blogger post I want to have add a spoiler tag/button thing where i can click ‘show spoiler’ and it will show the rest of the hidden text. Then be able to click ‘hide spoiler’ and have it hide the text again.

I’ve tried googaling it and I’ve tried a bunch of stuff but its not working but don’t get it.

Is there an easy way to do this?

Thanks in advance <3

Perhaps google something like “show hide button”.

How much control do you have to add HTML / CSS / JS to a blogger template?

Yeah i should have mentioned I have like no knowledge of control and html this is the site i used the last time i had trouble with all that.

it seems like people around here know what there talking about

Yep. The first question will be to find out what access you do have to the Blogger template, because normally you’d do this with JS, but that won’t help you if you can’t add JS to the template. I have a vague memory that you can’t, but I’m not familiar with Blogger.
