When working with CSS, it's common to encounter situations where multiple selectors are applied to the same element, leading to confusion about which selector takes precedence. Understanding CSS specificity is key to resolving these conflicts.
The specificity of a CSS selector determines how "specific" it is, and in turn, how likely it is to be applied. By calculating the specificity value of a given selector, we can easily determine which rule will override another.
1 . Inline Styles: These have the highest specificity and will override other styles, except for those marked as !important.
2 . IDs: An ID selector
3 . Classes, Attributes, and Pseudo-Classes: These selectors share the same level of specificity.
4 . HTML Tags and Pseudo-Elements: These have the lowest specificity.
Make this process easier, you can use a tool that calculates the specificity value for any given selector. You can even add multiple selectors by pressing the "+" button. The result section will display the selectors in order of specificity, making it clear which one takes precedence. Understanding this hierarchy can help eliminate confusion and make styling more predictable and manageable.
