</select>

  </tr>
</table>

To create a tooltip, you can use the title attribute on an HTML element. When the user hovers over the element, the tooltip text will be displayed.

```

### 5- Explain the purpose of the meter element in HTML5. <a name="5"></a>

The `<meter>` element represents a scalar measurement within a known range. It is commonly used to display measurements, such as disk space usage or progress indicators.

```

### 6- Explain the purpose of the `<datalist>` element in HTML5. <a name="6"></a>

```

### 8- How can you disable the browser’s default form validation in HTML? <a name="8"></a>
