<output name="result" for="a b">Sum: 100</output>
</form>
</body>
    

<p> (Paragraph)

The element is used to define a paragraph in HTML. It represents a block of text where the content is typically separated by space and newlines. Browsers typically render paragraphs with space above and below to visually separate them from surrounding content.

The element is used to provide multiple sources for an image and allows the browser to choose the most appropriate one based on factors such as the user's screen size, resolution, and other capabilities. It is commonly used in responsive web design to serve different image files for different scenarios.

Example


<picture>
<source media="(min-width: 800px)" srcset="large-image.jpg">

<img src="small-image.jpg" alt="A responsive image">
</picture>
    

<pre> (Preformatted Text)

The element is used to define preformatted text in HTML. Text within a element is displayed in a fixed-width font (usually Courier), and whitespace, such as spaces and line breaks, is preserved. This makes it suitable for displaying code snippets, poetry, or any text where formatting and spacing are crucial.

Example


<body>
<h2>Code Example</h2>
<pre>
function greet() {
console.log("Hello, World!");
}
greet();
</pre>

<h2>Poetry</h2>

And miles to go before I sleep,
And miles to go before I sleep.
</pre>
</body>

Example


<body>
<h2>File Upload Progress</h2>
<label for="file">Select a file:</label>
<input type="file" id="file" name="file">
<br>
<progress id="uploadProgress" value="30" max="100">30%</progress>

Example


<body>
<p>Japanese word for cat: <ruby>猫<rp>(</rp><rt>Neko</rt><rp>)</rp></ruby></p>
<p>Chinese character for water: <ruby>水<rp>(</rp><rt>Shuǐ</rt><rp>)</rp></ruby></p>
</body>
    

<s> (Strikethrough)

The element is used to represent text that has been strikethrough or marked for deletion. It indicates that the text within the element is no longer accurate or should be ignored. It is often used to visually represent changes in documents, such as edited or deleted content.

<script>
function greet() {
  alert('Hello, World!');
}
</script>

<p slot="content">This is custom content.</p>
</my-custom-element>

<script>
customElements.define('my-custom-element', class extends HTMLElement {
connectedCallback() {

    <slot name="content"></slot>
  `;
}
});
</script>
</body>          
    

<small> (Side Comment)

The element is used to define smaller text within the content of an HTML document. It is often used to represent fine print, legal text, or any content that should be displayed in a smaller font size without conveying a change in importance.

<html>            
<head>
<title>Span Element Example</title>
<style>
.highlight {

</html>            
    

<strong> (Strong Importance)

The element is used to define text with strong importance or importance that is more significant than the surrounding text. By default, browsers usually render text within <strong> tags as bold, but the primary purpose is to convey importance rather than styling.

Example


<p>This is a <strong>strongly emphasized</strong> statement.</p>
<p><strong>Caution:</strong> Handle with care.</p>
    

<style> (Style Information)

The element is used to embed or link to styles (CSS) within an HTML document. It can be placed in the of the document to define internal styles directly or can be used to link to an external CSS file.

The element is used to declare HTML content that can be cloned and inserted into the document later using JavaScript. The content inside a <template> element is not rendered when the page loads and remains inert until activated. It is a way to define reusable content or content that should not be displayed initially.

Example


<body>
<template id="myTemplate">
<p>This is a template content.</p>
</template>

Example


<h2>Sample Video</h2>
<video width="640" height="360" controls>
<source src="sample.mp4" type="video/mp4">
<source src="sample.webm" type="video/webm">
Your browser does not support the video tag.
</video>
    

<wbr> (Word Break Opportunity)

The element is used to suggest a possible word break in a long string of text without adding a visible character. It is particularly useful for preventing long words or strings of characters from overflowing beyond the boundaries of their container. The browser can choose an appropriate place to break the word if needed.

Example


<p>This is a longwordthatmayneedtobebroken using <wbr>the <wbr><wbr> element.</p>
