Exploring advanced HTML elements and their usage

HTML includes a variety of advanced elements that enhance the structure and functionality of web pages. This tutorial explores advanced HTML elements and their usage.

The <details> and <summary> Elements

The <details> element creates a disclosure widget, which can be used to hide or reveal additional information. The <summary> element defines a visible heading for the <details> element. Here is an example:

<details>
    <summary>More Information</summary>
    <p>This is additional information that can be revealed or hidden.</p>
</details>
            

The <dialog> Element

The <dialog> element represents a dialog box or other interactive component, such as an inspector or window. Here is an example:

<dialog id="dialog">
    <p>This is a dialog box.</p>
    <button onclick="document.getElementById('dialog').close()">Close</button>
</dialog>

<button onclick="document.getElementById('dialog').showModal()">Open Dialog</button>
            

The <progress> Element

The <progress> element represents the completion progress of a task. Here is an example:

<progress value="70" max="100">70%</progress>
            

The <meter> Element

The <meter> element represents a scalar measurement within a known range, or a fractional value. Here is an example:

<meter value="0.6">60%</meter>
            

The <output> Element

The <output> element represents the result of a calculation or user action. Here is an example:

<form oninput="result.value=parseInt(a.value)+parseInt(b.value)">
    <input type="range" id="a" value="50"> +
    <input type="number" id="b" value="50"> =
    <output name="result" for="a b">100</output>
</form>
            

The <template> Element

The <template> element is used to declare fragments of HTML that can be cloned and inserted in the document by JavaScript. Here is an example:

<template id="my-template">
    <div>This is a template</div>
</template>

<script>
    const template = document.getElementById('my-template');
    const clone = document.importNode(template.content, true);
    document.body.appendChild(clone);
</script>
