Superscript and subscript in css?

Yes, but as specified in the initial request: "I don't like the ^{tag because it shifts my line spacing by half a point, creating a line spacing of one and a half.}"

Hello,

could you please tell me what to do?
there isn't necessarily a perfect solution for everything…

what have you tried?
do you have an online version of your attempts?

Hello,

This is an issue I’ve been looking into for many years (summary of my posts on the subject: http://david.latapie.name/blog/tag/exposant)

I haven't found an ideal solution, but here is the complete set of CSS rules I use:

sup {line-height:80%;font-size:82%}

Thank you for your feedback!

you can also write directly after the text:

example¹ and example², that is (I'll break it down) & sup 1 ; and & sup 2 ;

this avoids having to write a tag, and the text is placed in the same line spacing as the text.
limited to 1, 2, and 3.

No, no, and no.

1. No, because all the numbers are available. However, the numbers 4 to 0 are not located in the same place in Unicode (you're using Unicode, right? You're not stuck in the 20th century?)

The list is here, with superscripts and subscripts

¹²³????????????????

(horror: howcamarche.net doesn’t even use Unicode. Guys, that’s not professional – Unicode dates back to 1990! – after the 3 in superscript, you’re supposed to see the other superscripts followed by the subscripts)

2. No, because Unicode characters are not designed to be used, but to be compatible with existing ones. For example, there are Unicode characters for Roman numerals, but they are not intended to be used in new documents, just to allow old documents to be read (for a Roman numeral, it is recommended to use the corresponding Latin characters (I, II, III, IV...), even though the Roman numeral exists in Unicode (?,?,?,?...

3. No, because doing so leads to double standards: for numbers, you use Unicode characters, and for letters, mmh? And there you are, having to mix exponent characters and CSS, instead of using CSS everywhere (since it is impossible to use exponent characters everywhere).

Hoping to have been helpful.

oh cool there's no need to get worked up like that. I have Dreamweaver and I'm making do with it; I didn't position myself as a specialist either.
well I found this that I'm finally going to use for my superscripts:

in the CSS:

sup {

valign: super;
font-size: 70%;
line-height: 80%;
}

the line spacing is not affected and the number stands out better.
is it the 21st century now?
