Creating several HTML elements from a single customized tag

I'm interested in being able to write something like:

<mycustomtag>bob</mycustomtag>

And have it produce:

<div>I'm a template <h2>bob</h2> </div>

Do you think it's possible to achieve this?

Just to clarify, I am not considering using JavaScript for this task. I am solely looking into accomplishing this with plain HTML/CSS. Is it technically feasible for an HTML element to create more elements via CSS alone?

Answer №1

If you want to achieve a specific effect that can't be done with just HTML and CSS, JavaScript will need to be utilized.

One possibility using only HTML and CSS is to make use of the ::before and ::after pseudo-elements:

mycustomtag {
  display:block;
}

mycustomtag::after {
  content:'extra element here';
  display:block;
}

Here's an example
