CSS Interview Questions
1. What is CSS?
CSS stands for Cascading Style Sheets. It is used to style the look and formatting of HTML documents, providing a powerful way to control the presentation of web content.
2. What are the advantages of using CSS?
- CSS makes it easier to maintain consistent presentation across multiple pages.
- CSS can save time, since complex styling can be done in minutes instead of hours.
- CSS enables web designers to separate content from presentation.
- CSS reduces page load times, since code is written separately from HTML.
- CSS can reduce the need to use HTML tables for layout.
- CSS can be used to achieve fonts and color schemes that are not available in HTML.
3. What are the different types of CSS?
There are three types of CSS: internal, external, and inline.
- Internal CSS is contained within an HTML document, written between the <head></head> tags and usually marked by the <style></style> tags.
- External CSS is stored in a separate file with a .css extension, and linked to an HTML page via the <link> tag.
- Inline CSS is applied directly to an HTML element via the
styleattribute.
4. What is the difference between classes and ids in CSS?
Classes and ids are both ways to identify elements and assign styles to them. The difference between them is that a class selector can be applied to multiple elements, while an id selector can only be applied to one element.
5. What is the purpose of the * selector in CSS?
The * selector in CSS is a universal selector, meaning it selects all elements on a page. It is often used as a reset style, to ensure that all elements have a consistent starting point before being styled individually.
