Changing Table Row Background Color with CSS Classes

Tables are an essential part of displaying data on web pages, serving as a neat, organized way to present information. However, sometimes you might want to highlight certain rows to make them stand out – perhaps for better readability or to draw attention to specific data points. In this guide, we'll explore how to change the background color of table rows using CSS classes.

Understanding the Problem

You may have encountered a situation where you applied a CSS class to table rows but found that the background color didn't change as expected. This often happens due to incorrect CSS selectors or specificity issues. Let's dive into how to solve this problem.

Identifying the Issue

The CSS selector .main-table tbody td .main-table-row is incorrect because it specifies that the main-table-row class must be a descendant of a td element, which is not the case in our HTML structure. Instead, we want to directly apply the background color to the tr elements with the class main-table-row.

The Solution

To properly apply the background color to the desired table rows, we need to correct the CSS selector. Here’s the updated version:
