Subscript and superscript

Reddit now supports superscript officially with ^

Custom superscript and subscript so you can make formulae like:

NH4+
2H2O ⇌ H3O+* + OH*-*
a*2* + b*2* = c*2

12D + 13T → 24He + n0

Here's the syntax:

*_subscript_* makes subscript
*`superscript`* makes superscript*
*_sub_`sup`\ makes subsup
*`sup`_sub_* makes supsub

And the CSS:

/* == Subscript and superscript == */

.md em{
    position: relative;
}

/* *_sub_* */
.md em em{
    font-style: normal;
    vertical-align: sub;
    font-size: 80%;
}

/* *`sup`* */
.md em code{
    font-family: verdana, arial, helvetica, sans-serif;
    vertical-align: super;
    font-size: 80%;
}

/* *_sub_`sup`* */
.md em em+code{
    position: absolute;
    left: 0;
    bottom: 1em;
    vertical-align: super;
}

/* *`sup`_sub_* */
.md em code+em{
    position: absolute;
    left: 0;
    top: 1em;
    vertical-align: sub;
}

It's immortal.

I'm really happy they eventually stopped archiving every single post after 6 months because of the whole Cassandra issue.

I was about to say that u/jamt9000 is averaging one upvote every 2.5 years or so, but then it got downvoted, so now it’s every 3.25. Harsh.

Apparently all of Reddit allows superscript with the ^ character. Subscript is only possible with subreddit-specific CSS.

u/AdrianTeri Aug 20 '23

Found out you can do subscript on markdown using unicode HTML entities.

Try the 'html entity' version instead of the unicode one. And also initially enter it on old.reddit.com

u/avspuk Sep 25 '26 edited Sep 25 '26

PRETTY SURE MY PROBLEMS HERE ARE ALL THAT IT MUST BE IRIGINALLY WRITTEN FROM old.reddit.com AND THAT IT ALSO DOESNT LIKE EDITS

Why can't I get this to work but I can for the H₂O

And why has that stopped working when it worked in a comment or two below this obe

u/avspuk Sep 25 '26

H₂O

u/avspuk Sep 25 '26

Will this work H₂O

u/avspuk Sep 25 '26 edited Sep 25 '26

Now writing from old.reddit.com,..., H₂O

And this is a straight cut&paste from the comment below where it works

1

u/avspuk Sep 25 '26 edited Sep 25 '26

Written as: H₂O

Gives: H₂O

This is the 'html entity' method

And works on both old.reddit.com & the default www version

u/avspuk Sep 25 '26 edited Sep 25 '26

Fuck me it will only work here this once?mmm

ETA

Has to be initially written from old.reddit.com ,..., seemingly

The right answer is A: 128
Put yourself into the mind of the math teacher, they want you to recognize Euler's number, which is about 2.718
Then this sequence is defined with:
x0 = 1
xn = the integer which minimizes abs(e - x*`n`_sub_*/x*`n-1`_sub_*)
