Specificity and priority determine which CSS rule is applied when multiple rules target the same element. Understanding this concept is essential for writing clean, predictable styles.<\/p>\n\n\n\n
Specificity is a ranking system used by the browser to decide which CSS rule is more important. Each selector type has a different weight.<\/p>\n\n\n\n
Inline styles have the highest specificity. They are written directly inside HTML elements using the style attribute.<\/p>\n\n\n\n
ID selectors are very strong and override class and element selectors.<\/p>\n\n\n\n
Class selectors, attribute selectors, and pseudo classes have medium strength.<\/p>\n\n\n\n
Element selectors and pseudo elements have the lowest strength.<\/p>\n\n\n\n
Inline styles override everything else.<\/p>\n\n\n\n
ID selectors override class selectors and element selectors.<\/p>\n\n\n\n
Class selectors override element selectors.<\/p>\n\n\n\n
Element selectors have the lowest priority.<\/p>\n\n\n\n
p {
color: blue;
}.text {
color: green;
}#title {
color: red;
}<\/pre>\n\n\n\nIf all these rules target the same paragraph, the text will appear red because the ID selector has higher specificity.<\/p>\n\n\n\n
What is CSS Priority<\/h3>\n\n\n\n
Priority refers to the order in which styles are applied when specificity is equal.<\/p>\n\n\n\n
When two selectors have the same specificity, the rule written last in the CSS file will be applied.<\/p>\n\n\n\n
Example of Priority<\/h3>\n\n\n\np {
color: blue;
}p {
color: green;
}<\/pre>\n\n\n\nThe paragraph will be green because the second rule comes later.<\/p>\n\n\n\n
Important Rule<\/h3>\n\n\n\n
The important keyword overrides all other rules, regardless of specificity.<\/p>\n\n\n\n
p {
color: blue !important;
}#title {
color: red;
}<\/pre>\n\n\n\nThe text will remain blue because the important rule takes priority.<\/p>\n\n\n\n
How Specificity is Calculated<\/h3>\n\n\n\n
Inline styles have the highest value.<\/p>\n\n\n\n
ID selectors have higher value than classes.<\/p>\n\n\n\n
Classes have higher value than elements.<\/p>\n\n\n\n
The browser compares these values to decide which rule to apply.<\/p>\n\n\n\n
Best Practices<\/h3>\n\n\n\n
Avoid using the important keyword unless absolutely necessary.<\/p>\n\n\n\n
Use classes instead of IDs for better flexibility.<\/p>\n\n\n\n
Keep your CSS simple and organized.<\/p>\n\n\n\n
Write styles in a logical order to avoid conflicts.<\/p>\n\n\n\n
Summary<\/h3>\n\n\n\n
Specificity decides which rule is stronger.<\/p>\n\n\n\n
Priority decides which rule is applied when strength is equal.<\/p>\n\n\n\n
Understanding both helps you control your website design more effectively.<\/p>\n\n\n\n
