Why Css Doesn’t Recognize Four Classes

CSS Programming

Hi there! Today, I want to discuss a common issue that many web developers encounter when working with CSS. Have you ever tried to apply styling to multiple elements using four classes, only to find that it doesn’t work as expected? Well, you’re not alone! In this article, I will explain why CSS doesn’t recognize four classes and explore some possible workarounds.

The Problem with Four Classes in CSS

Before we dive into the details, let’s first understand how CSS works. Cascading Style Sheets (CSS) is a language used to describe the look and formatting of a document written in HTML. It allows web developers to apply styles to HTML elements, such as changing colors, fonts, and layout.

When applying styles to elements, we often use class selectors to target specific elements and apply specific styles to them. For example, if we have four elements that we want to style in a similar way, we can assign them the same class name, say “my-class”, and define the styles for that class in the CSS file.

However, CSS has a limitation when it comes to applying styles using four classes. Due to the way CSS is designed, it only allows for one class to be applied to an element at a time. This means that if you try to assign four classes to an element, only the styles of the last class declared will be applied.

For example, let’s say we have the following CSS code:

.my-class1 { color: blue; }
.my-class2 { font-weight: bold; }
.my-class3 { background-color: yellow; }
.my-class4 { text-decoration: underline; }

And we want to apply all these four classes to a single element, like this:

<div class="my-class1 my-class2 my-class3 my-class4">Some content</div>

Unfortunately, in this case, only the styles defined in .my-class4 will be applied, and the styles from the other three classes will be overridden. This can be frustrating, especially when you have carefully defined styles for each class that you want to apply simultaneously.

Possible Workarounds

While CSS doesn’t provide a direct solution to apply styles using four classes, there are several workarounds that you can use to achieve similar results. Here are a few options:

  1. Combine the Styles in a Single Class: Instead of using four separate classes, you can define a single class that combines the styles you want to apply. This way, you can apply all the desired styles to an element by assigning just one class. However, this approach may become difficult to maintain if you have many different combinations of styles.
  2. Use CSS Preprocessors: CSS preprocessors like SASS or LESS allow you to write more dynamic and modular CSS code. With preprocessors, you can define variables and mixins to easily apply multiple styles to elements. They provide more flexibility in handling complex styling scenarios and can be a good alternative if you frequently need to apply multiple classes.
  3. Consider Inline Styles: While it’s generally not recommended to use inline styles, as it may lead to code duplication and reduced maintainability, it can be an option in certain cases. By directly applying styles to the HTML elements using the style attribute, you can bypass the limitation of applying styles using multiple classes. However, be cautious as this approach can make your code less organized and harder to manage.


While CSS doesn’t natively support applying styles using four classes, there are various workarounds to achieve similar results. Combining styles in a single class, using CSS preprocessors, or considering inline styles are some possible solutions.

Ultimately, the choice of which workaround to use depends on the specific requirements of your project and your personal coding preferences. Just keep in mind that when using workarounds, it’s essential to consider the maintainability and organization of your code.

I hope this article shed some light on why CSS doesn’t recognize four classes and provided you with some useful insights. Happy coding!
