How can I use CSS to highlight a row?

You can use CSS to highlight a row in a table or any other HTML structure by applying styles to the row element, typically a <tr> element in a table. Here's how you can achieve this:

1. Basic Highlighting with Background Color:

- The most common way to highlight a row is by changing its background color. You can do this using the background-color property.

- Example:

tr:hover {
  background-color: #f0f0f0; / Light gray on hover /
}

- This CSS snippet will change the background color of a table row when the mouse hovers over it. You can adjust the color to your preference.

2. Highlighting with a Border:

- Another way to highlight a row is by adding a border. This can be done using the border property.

- Example:

tr:hover {
  border: 2px solid #007bff; / Blue border on hover /
}

- This will add a blue border around the row when hovered over. You can customize the border's width, style, and color.

3. Combining Background Color and Border:

- You can combine both background color and border for a more pronounced highlight effect.

- Example:

tr:hover {
  background-color: #e6f7ff; / Light blue background /
  border: 1px solid #007bff; / Blue border /
}

- This will give the row a light blue background and a blue border when hovered over.

4. Using Specific Classes:

- If you want to highlight specific rows based on certain conditions, you can add a class to those rows and target that class in your CSS.

- Example:

.highlighted-row {
  background-color: #fff0e6; / Light orange background /
}

- Then, in your HTML, you would add the class highlighted-row to the <tr> element you want to highlight.

5. Using JavaScript for Dynamic Highlighting:

- For more complex scenarios, you might use JavaScript to dynamically add or remove highlight classes based on user interaction or data changes.

By using these CSS techniques, you can effectively highlight rows in your HTML tables or other structures, improving user experience and data visibility. Remember to choose colors and styles that are consistent with your website's design and accessibility guidelines.
