Why Is My Content Not Hiding?

If you've been developing web pages, you might have come across a situation where you want to toggle content's visibility via JavaScript. You click a button, and you expect the content to disappear, but it's still there. Why?

This common issue often arises from conflicting CSS properties. Let's break down how to solve this problem and ensure your content behaves as expected.

Understanding the Problem

In the provided example, JavaScript is used to add a class named hide to a content element when a button is clicked. The intention is to use CSS to hide the element by setting display: none; when the hide class is present.

However, if the CSS for the .content has a conflicting display property, it can prevent the content from hiding. In this case, the standard .content class may have a different display setting that overrides the hide class.

The Solution

1. Make Your Selector More Specific
