HTML: <mark> tag

In this series of learning HTML, we will teach you how to use HTML mark tag with proper syntax and lots of examples. Let’s start on the HTML mark tag.

Description of HTML mark tag

The HTML “mark” tag is a semantic tag introduced in HTML5 that is used to highlight or emphasize text on a web page. When this tag is used, the enclosed text is typically rendered by the web browser as highlighted or with a yellow background, although the exact appearance may vary depending on the browser and user agent.

The syntax for using the “mark” tag is quite simple. To mark a section of text, simply wrap it in the opening and closing “mark” tags, like so:

Syntax of HTML mark tag

The HTML <mark> tag is used to highlight a section of text on a webpage. Here’s the basic syntax of the <mark> tag:

<mark>Highlighted text</mark>

The text that you want to highlight goes between the opening and closing tags. You can also use CSS to style the <mark> tag as per your requirement.

Event Attributes

The <mark> tag is used in HTML to highlight text that has special emphasis or importance within a block of text. When the <mark> tag is used, the enclosed text is typically displayed in a distinctive color (usually yellow) or with other styling, such as a darker background or bolded text.

The <mark> tag is an inline element, which means that it should be used within a block-level element, such as a paragraph or a heading. It does not create a new line or break up the flow of text.

Here are some common attributes used with the <mark> tag:

• class: This attribute is used to define a class name for the element, which can be used to apply CSS styles to the element.
• id: This attribute is used to give the element a unique identifier, which can be used to link to the element or apply styles to it using CSS.
• title: This attribute is used to provide additional information about the element, which is displayed as a tooltip when the user hovers over the element with their mouse.
• style: This attribute is used to apply inline styles to the element, such as changing the color or background color of the highlighted text.
• data-*: This is a custom attribute that allows you to add your own data to the element. You can replace the asterisk with any name you choose, and the attribute value can be any valid string. This attribute is often used to store data that is not visible to the user, but can be accessed and manipulated using JavaScript.

Other Attributes

The <mark> tag in HTML does not have any specific attributes other than the global attributes that can be used with any HTML element.

Global attributes are the attributes that can be used with any HTML element, such as class, id, style, title, and data-*. These attributes provide a way to add metadata, style, and functionality to the elements of an HTML document.

However, it’s worth noting that the use of attributes like class, id, and style can be particularly useful with the <mark> tag, as they allow you to apply specific styling or functionality to the highlighted text.

For example, you can use the class attribute to create a CSS class that applies a specific background color and text color to the <mark> element, like this:

<style>
.highlight {
background-color: yellow;
color: black;
}
</style>

<p>This is some <mark class="highlight">highlighted</mark> text.</p>

You can also use the id attribute to create a unique identifier for the <mark> element, which can be used to link to the element from elsewhere in the document, like this:

<p>Click <a href="#highlight">here</a> to jump to the highlighted text.</p>

<p>This is some <mark id="highlight">highlighted</mark> text.</p>

In summary, while the <mark> tag does not have any specific attributes other than the global ones, the use of attributes like class, id, and style can be particularly useful when styling or adding functionality to highlighted text.
