When Should You Use the CSS `!important` Property?

When to Employ the !important Property in CSS

Inline styles can present challenges when coupled with global CSS styles, potentially overriding desired global settings. The !important property resolves this conflict by prioritizing globally defined styles.

Consider the following case:

#div p {
    color: red !important;
}
...
#div p {
    color: blue;
}
Copy after login

Despite the subsequent blue declaration, the 'red' declaration overrides it due to the !important property, ensuring the div element remains red.

Appropriate Utilization of !important

The !important property finds its niche in situations where you lack complete control over inline styles, such as:

  • Global CSS Overriding Inline Styles: If external styles are not under your direct control, you can use !important to ensure your global CSS styles take precedence over inline declarations.
  • Overriding Erroneous Styles: When imported CSS libraries introduce unintended inline styles, !important allows you to neutralize their effects and maintain desired visual attributes.

Cautions in Using !important

While !important can offer temporary solutions, it's crucial to exercise discretion when employing it. Overuse of !important compromises the natural cascading behavior of CSS and can complicate maintenance. Therefore, consider alternative solutions before resorting to this property.
