FAQ: Html Css Interview Questions
- What is the difference between HTML and CSS?
- HTML (HyperText Markup Language) is used for structuring content on the web, defining elements like headings, paragraphs, and images. CSS (Cascading Style Sheets) is used for styling the appearance of that content, controlling things like colors, fonts, layout, and responsiveness.
- Why is it important to use semantic HTML?
- Semantic HTML uses tags that convey meaning about the content they enclose (e.g.,
<header>,<nav>,<article>,<footer>). This improves accessibility for screen readers, enhances SEO, and makes the code more readable and maintainable for developers. - How does CSS specificity work?
- CSS specificity is the algorithm browsers use to determine which CSS rule applies to an element when multiple rules target it. It's calculated based on the type of selector (inline style > ID > class/attribute/pseudo-class > element/pseudo-element), with higher specificity winning out.
- Can you explain responsive web design in simple terms?
- Responsive web design is an approach that makes web pages render well on a variety of devices and screen sizes, from desktop monitors to mobile phones. It's achieved using flexible layouts (Flexbox, Grid), fluid images, and CSS media queries to apply different styles based on screen characteristics.
