The <strong>
tag in HTML is used to indicate strong importance or seriousness in the text it wraps. Unlike simple styling tags, <strong>
adds semantic meaning by telling browsers and assistive technologies (like screen readers) that the content inside is important.
📌 What Is the <strong>
Tag?
- It is an inline semantic element that signals strong emphasis.
- By default, browsers render
<strong>
text in bold. - Important for accessibility and SEO because it highlights key information.
✅ Basic Syntax
<p>Please read the <strong>terms and conditions</strong> carefully.</p>
This renders the phrase terms and conditions in bold and signals importance.
🧪 Example 1: Highlighting Warning Text
<p><strong>Warning:</strong> Do not share your password with anyone.</p>
🧪 Example 2: Emphasizing Key Points
<p>Your order will be shipped within <strong>3-5 business days</strong>.</p>
🎨 Styling <strong>
Though browsers default to bold styling, you can customize <strong>
via CSS:
strong {
color: red;
font-weight: bolder;
}
⚙️ Accessibility and SEO Benefits
- Screen readers typically read
<strong>
content with a stronger voice or tone. - Search engines may weigh
<strong>
text as more important content.
