The HTML <u> tag is used to underline text in a webpage. It is primarily used to emphasize a section of text or distinguish it from other parts of content. In modern web development, underlined text can sometimes be confused with hyperlinks, so it's recommended to use it thoughtfully to avoid user confusion. The <u> tag was originally used for underlining text, but now it's used to represent text that has a non-textual annotation or a specific stylistic emphasis.
Syntax of the <u> Tag
<u>Underlined Text</u>
When placed inside the <u> tag, the text will appear underlined in most browsers. The tag can be applied to any inline text element such as paragraphs, headings, or span elements.
Attributes of the <u> Tag
The <u> tag does not have any specific attributes that directly control its behavior. However, like most HTML tags, it supports global attributes that allow developers to further customize its usage.
| Attribute | Description |
|---|---|
| class | Specifies a class name for the tag, allowing the element to be styled with CSS. |
| id | Defines a unique identifier for the element, which can be referenced in JavaScript or CSS. |
| style | Allows inline CSS styling of the element. For instance, you can style the underlined text's color. |
| title | Adds a tooltip that appears when the user hovers over the underlined text. |
Using CSS with the <u> tag allows for a more precise and controlled visual presentation, especially for color, style, and additional formatting.
Examples of HTML <u> Tag
Example 1: Basic Underlined Text
<!DOCTYPE html>
<html>
<head>
<title>Basic Underlined Text</title>
</head>
<body>
<p>This is an example of <u>underlined text</u> in HTML.</p>
</body>
</html>
In this example, the word "underlined text" will appear with an underline in most web browsers, adding emphasis to the text.
Example 2: Underlined Text with CSS Styling
<!DOCTYPE html>
<html>
<head>
<title>Underlined Text with Style</title>
<style>
.custom-underline {
color: red;
text-decoration: underline;
}
</style>
</head>
<body>
<p>This is a <u class="custom-underline">custom styled underlined text</u> with CSS applied.</p>
</body>
</html>
In this example, the <u> tag is enhanced with CSS to apply a red color to the underlined text, showcasing the flexibility of using the tag in combination with modern styling techniques.
