Questions & Answers

Q: What is CSS?

CSS stands for Cascading Style Sheets and is a style sheet language used to describe the presentation of a document, primarily HTML. It is responsible for the visual appearance of a webpage.

Q: What are the different ways to apply CSS to a document?

CSS can be applied externally using an external style sheet, internally using a style element within the HTML document, or inline with the element itself.

Q: How does the cascade in CSS work?

CSS follows a cascade mechanism where styles are applied from top to bottom in the order they are defined. If two styles conflict, the more specific one takes precedence. The cascade allows for easy organization and prioritization of styles.

Q: What are the most commonly used CSS units?

The most commonly used CSS units are pixels (px), percentages (%), and relative length units like rems (relative to the root element) and ems (relative to the element's font size).

Q: What is the importance of contrast in CSS?

Contrast is crucial for ensuring legibility and accessibility on a webpage. It refers to the difference in brightness and color between text and background. Proper contrast ratios should be maintained to ensure readability for all users.

Q: How can you check the contrast ratio on a webpage?

There are tools available, such as the Coolers color palette generator and the WebAIM Contrast Checker, that can calculate the contrast ratio between text and background colors to ensure accessibility requirements are met.
