1 - What is the difference between inline and block elements in HTML?
Inline elements do not start on a new line and only take up as much width as necessary. Examples include <span> and <a>. Block elements, on the other hand, start on a new line and take up the full width available. Examples include <div> and <p>.
2) Explain the box model in CSS.
The box model consists of content, padding, border, and margin. Content is where the text and images appear, padding is the space between the content and the border, border surrounds the padding and content, and margin is the space outside the border. Understanding the box model is crucial for controlling the layout and spacing of elements on a webpage.
3) What is the difference between margin and padding in CSS?
Margins are used to create space outside an element's border, whereas padding is used to create space inside an element's border. Margins affect the space between elements, while padding affects the space between an element's content and its border.
4) How do you vertically center an element in CSS?
To vertically center an element, you can use techniques like using flexbox, setting the element to position: absolute and using top: 50% along with transform: translateY( 50%), or by using the calc() function along with flexible units like viewport height (vh).
5) What is the importance of media queries in CSS?
Media queries allow web developers to apply different styles for different screen sizes and devices. This helps create responsive web designs that adapt to various viewport sizes, ensuring a consistent user experience across desktops, tablets, and mobile devices.
