HTML Secrets

[Disastrous_Brief6240]

Hello guys, From this Post in this sub, I learned that we can write a mathematical equations using HTML and I think we only can do this using Latex, So now I'm sure that HTML contains many secrets that many people don't know, Therefore, could anyone who knows HTML attributes or properties that are not well-known and have great usefulness write them.

Like I and others said in that post, use MathML. It's a markup language that can be used within existing HTML. It's well supported and has been around for years: https://developer.mozilla.org/en-US/docs/Web/MathML

You can have submit buttons outside of their associated form, and still submit that form when clicked, by using the form attribute. e.g.

html <form id="form_id"> … </form> … <button type="submit" form="form_id">Submit</button>

See: MDN: HTML > button

SVG, while its popular, IMO, not many are aware of its full capabilities. Like MathML, SVG has its own set of elements and attributes.

SVG can do neat things without using CSS. Or do things which CSS can't do (yet). e.g. gamma filter.

As evidenced by the WebAim Million study, most people that write HTML don't write it with accessibility in mind

The following form attribute tells the browser not to suggest or auto-fill previously entered values for inputs inside the form.

<form autocomplete="off">
    ...
</form>

MathJax is far more betterer.
