عنصر anchor وسمته href

ما الرابط؟

السمة href

<a href="https://example.com">Visit Example</a>
<a href="/about">About Us</a>
<a href="../contact.html">Contact</a>
<!-- href = destination URL or path
     Content between tags = clickable text -->
<!-- Without href, a is still valid but not a hyperlink -->

أهمية نص الرابط

<!-- Bad: uninformative -->
<a href="/docs/guide">Click here</a>
<a href="/docs/guide">Read more</a>

<!-- Good: descriptive -->
<a href="/docs/guide">Read the Getting Started Guide</a>

<!-- Screen readers list all links — "click here" is meaningless out of context -->

أنواع قيم href

<a href="https://example.com">External URL</a>
<a href="/page">Root-relative path</a>
