Tag span

The <span> tag in HTML is a generic inline container used to group and apply styles or attributes to a part of text or document without adding any special meaning. It’s perfect when you want to target or style a small section of content inside a block element.

📌 What Is the <span> Tag?

• <span> is an inline element with no semantic meaning.
• It groups inline elements or text so CSS or JavaScript can be applied.
• Unlike <div>, which is block-level, <span> stays inline with the text.

✅ Basic Syntax

<p>This is a <span style="color: red;">red</span> word.</p>

Result:
This is a red word.

🧪 Example 1: Highlighting Text

<p>Warning: <span class="highlight">High voltage</span> area.</p>

<style>
  .highlight {
    background-color: yellow;
    font-weight: bold;
  }
</style>

---

🧪 Example 2: Adding JavaScript Interaction

<p>Click <span id="clickMe" style="color: blue; cursor: pointer;">here</span> to alert a message.</p>

<script>
  document.getElementById('clickMe').addEventListener('click', () => {
    alert('You clicked the span!');
  });
</script>

🎨 Styling <span> with CSS

Since <span> is an inline container, it is often used for:

• Changing text color or font
• Adding background highlights
• Adding tooltips or icons inline
• Attaching event listeners in JS
