CSS !important
The !important
rule in CSS is used to give a CSS property higher priority over other declarations. This allows you to override existing styles, regardless of their specificity. It should be used sparingly, as overuse can lead to difficulties in maintaining and debugging the CSS code.
Key Points on CSS !important:
- The
!important
flag makes a CSS rule more specific than other rules, even if they have a higher specificity. - It is generally considered a "last resort" for overriding styles when normal CSS specificity rules don't suffice.
- Use it with caution because it can make debugging and maintaining code difficult.
- The
!important
rule applies to individual CSS properties and not entire selectors. - If two conflicting rules both use
!important
, the one that appears later in the CSS will take precedence.
Syntax for CSS !important:
Syntax Example
/* Example of using !important */
color: red !important;

Examples of CSS !important:
The following examples demonstrate the usage of the !important
rule:
Code Example: Overriding Color with !important
div {
color: red !important;
background-color: yellow;
}
Output
This div has a red text color and yellow background, with !important overriding any conflicting styles.
Code Example: !important in Multiple Styles
div {
color: blue;
background-color: green !important;
}
Output
This div has blue text and a green background due to the use of !important on the background-color.
When to Avoid Using !important:
- Avoid using
!important
unless absolutely necessary, as it reduces maintainability. - Overusing
!important
can lead to difficulties in overriding styles in the future, particularly when dealing with third-party libraries or frameworks. - Consider revisiting the CSS structure and improving selector specificity before resorting to
!important
.
It is important to manage CSS with well-structured styles and avoid relying too much on !important
for better maintainability and readability.
