When To Use Important In Css

CSS Programming

Have you ever come across the CSS property !important and wondered when and how to use it? As a web developer, I have encountered this powerful tool numerous times. In this article, I will explain what !important does, when it is appropriate to use it, and provide some personal insights into its usage.

Understanding !important

In CSS, the !important keyword is used to give a style rule the highest priority. When applied to a CSS property, it ensures that the specified value is always used, overriding any other conflicting styles that might be applied.

For example, let’s say you have a specific element that is styled with a certain color, but you want to override that color for just this element. By using !important, you can make sure that your desired color takes precedence.

It is important to note, however, that using !important should be done sparingly and with caution. When overused, it can lead to a messy and hard-to-maintain codebase. It is recommended to only use it when absolutely necessary and as a last resort.

When to Use !important

There are a few scenarios where using !important could be justified:

  1. Overriding External Styles: When you are working on a project that includes external stylesheets, you might encounter conflicts with certain styles. In such cases, using !important can help you quickly and easily override those conflicting styles without modifying the external stylesheet. It provides a convenient way to ensure that your styles take precedence, saving you time and effort.
  2. Resolving Specificity Issues: CSS follows a specificity hierarchy where certain selectors take precedence over others. However, there are instances where you might need to override a style that has a higher specificity. In these cases, using !important can be a reliable solution to make your desired style prevail.
  3. Accessibility Requirements: Ensuring accessibility is an important aspect of web development. Sometimes, you might need to use !important to override styles that can hinder accessibility, such as low contrast colors or insufficient font sizes. However, it is essential to thoroughly test your changes to ensure they do not negatively impact other aspects of accessibility.

Personal Insights

As a developer, I have found !important to be a double-edged sword. While it can be a convenient tool in certain situations, it can also lead to confusion and conflicts if not used judiciously. Overusing !important can make your CSS code difficult to maintain, especially when working on collaborative projects or when trying to troubleshoot an issue.

When faced with a situation where I need to use !important, I always try to explore other alternatives first. Modifying the CSS selector specificity, restructuring the HTML markup, or using more targeted selectors can often achieve the desired result without resorting to !important. However, there are times when using !important is the most practical and efficient solution.


In conclusion, !important is a powerful tool in CSS that can help you override conflicting styles and ensure that your desired styles take precedence. While it should be used sparingly and with caution, there are certain scenarios where it is justified and can save you time and effort. As with any CSS technique, it is important to strike a balance between convenience and maintainability. By understanding when and how to use !important, you can effectively leverage this tool while keeping your codebase clean and manageable.
