FAQs
1. What is the difference between inline, internal, and external CSS?
Inline CSS is written inside HTML tags, internal CSS is placed within a <style> tag in the head, and external CSS is stored in a separate file and linked to the HTML. External CSS is preferred for maintainability.
2. What is the cascading order in CSS?
CSS applies rules in a cascading manner: browser default → external → internal → inline. Specificity, importance (!important), and source order also affect which styles are applied.
3. What is the box model in CSS?
The box model describes how elements are structured with content, padding, border, and margin. Understanding it is essential for layout and spacing.
4. What is specificity in CSS?
Specificity determines which rule takes precedence when multiple rules target the same element. Inline styles > ID selectors > Class selectors > Element selectors.
5. What is the difference between Flexbox and Grid?
Flexbox is best for one-dimensional layouts (row or column), while Grid is suitable for two-dimensional layouts (rows and columns together).
6. How do media queries work in CSS?
Media queries apply styles based on device conditions like screen width. They are essential for creating responsive websites.
7. What are pseudo-classes and pseudo-elements?
Pseudo-classes like :hover and :focus apply styles based on user interaction. Pseudo-elements like ::before and ::after style specific parts of an element.
8. Why should you avoid using !important frequently?
Using !important overrides all other rules, which can make debugging harder and affect maintainability. Use it only when absolutely necessary.
9. What tools can enhance writing CSS?
Tools like SASS, LESS, Tailwind CSS, and PostCSS help in writing cleaner, more scalable CSS with features like nesting, variables, and mixins.
10. How can CSS impact website performance?
Efficient CSS can improve load time and user experience. Avoid unnecessary styles, minimize CSS files, and use compression tools like cssnano.
