How to write text in small font [duplicate]

Question

I remember seeing some questions and answers in which some text was written in small fonts, but, I haven't found a matching tag in the whitelisted HTML tags. How did they do this?

Answer 1

I expect either the <sup> or <sub> tags, or a combination of both.

^{You know, like this?}

_{Or this?}

^{_{Or even, this.}}

<sup>You know, like this?</sup>

<sub>Or this?</sub>

<sup><sub>Or even, this.</sub></sup>

Answer 2

_{This was just a miracle and you didn't actually see any small fonts, ^{forget and relax :)}}

In other words, place your text in <sub></sub> or <sup></sup> tags. The first one is subscript, the second is superscript - but they are abused to make small text :D

You can also use multiple <sub>s or <sup>s, or combine them, that's what I've done in my example and the markdown is:

<sub>This was just a miracle</sub> <sub><sub>and you didn't actually see any small fonts, <sup><sup>forget and relax :)</sup> </sub></sub></sub>

And to let you understand the hierarchy :

<sub>
    This was just a miracle
</sub>
<sub>
    <sub>
        and you didn't actually see any small fonts,
        <sup>
            <sup>
                forget and relax :)
            </sup>
        </sup>
    </sub>
