The <mark> HTML element is used to highlight or mark a specific section of text within a document. It is commonly used to visually emphasize or draw attention to certain words or phrases.

Here’s an example of how to use the <mark> element:

<p>This is a <mark>highlighted</mark> word in a sentence.</p>

In this example, the word “highlighted” is wrapped within the <mark> element. When rendered in a web browser, the text within the <mark> element is typically displayed with a background color or other highlighting effect to make it stand out from the surrounding text.

The <mark> element can be used to indicate search results, keywords, or any important information that you want to visually emphasize. It does not have any semantic meaning on its own, but it provides a visual cue to attract attention.

It’s worth noting that the styling of the <mark> element can be customized using CSS to match the design of your website. You can define the background color, text color, and other visual properties to achieve the desired highlighting effect.

When using the <mark> element, it’s important to consider accessibility. Screen readers and other assistive technologies may not convey the visual styling of the element, so it’s recommended to provide additional context or alternative text to ensure the information is accessible to all users.
