HTML Text Formatting
When designing a webpage, text formatting plays a crucial role in improving readability and emphasizing important content. HTML provides various tags to format text, making it more visually appealing and accessible. In this guide, we’ll explore five essential HTML text formatting tags: <b>, <i>, <u>, <strong>, and <em>, along with practical examples.
1. The <b> Tag (Bold Text)
The <b> tag makes text bold without adding any extra importance to it. It’s useful for styling but does not impact SEO or screen readers.
Example:
<p>Welcome to <b>Web Development</b> tutorials.</p>Output:
Welcome to Web Development tutorials.
✅ Best Use Case: Use <b> when you want text to appear bold purely for visual emphasis.
2. The <i> Tag (Italic Text)
The <i> tag italicizes text, often used for stylistic purposes such as emphasizing technical terms, foreign words, or thoughts.
Example:
<p>My favorite book is <i>The Great Gatsby</i>.</p>Output:
My favorite book is The Great Gatsby.
✅ Best Use Case: Use <i> for stylistic emphasis, like book titles, scientific names, or phrases in different languages.
3. The <u> Tag (Underlined Text)
The <u> tag underlines text, but it is not commonly used in modern web design since underlining is often associated with links.
Example:
<p>Please read the <u>instructions carefully</u>.</p>Output:
Please read the instructions carefully.
✅ Best Use Case: Use <u> when highlighting spelling errors or indicating special content, but avoid using it for emphasis.
4. The <strong> Tag (Strong Emphasis – Bold + Semantic Meaning)
The <strong> tag makes text bold and also gives it semantic meaning, indicating that the enclosed text is of great importance. Search engines and screen readers recognize this as important content.
Example:
<p>Warning: <strong>Do not share your password.</strong></p>Output:
Warning: Do not share your password.
✅ Best Use Case: Use <strong> for important content like warnings, alerts, or crucial instructions.
5. The <em> Tag (Emphasized Text – Italic + Semantic Meaning)
The <em> tag italicizes text while conveying emphasis. It is often read with stress in screen readers, making it useful for accessibility.
Example:
<p>I <em>really</em> love coding.</p>Output:
I really love coding.
✅ Best Use Case: Use <em> for words that need verbal emphasis, such as expressing emotions or contrast.

Conclusion
