Q & A

What is the main objective of the session?

The main objective is to understand page layout customization using the CSS Box model, floating, absolute and fixed positioning, and alignment.

Why is it important to learn page layout customization?

Page layout customization is important because it helps create more complex and visually appealing web pages by organizing content effectively and designing better layouts.

What is the CSS Box model?

The CSS Box model is a concept in web development that determines how elements on a web page are structured, including content, padding, borders, and margins.

What steps are recommended when creating a web page layout?

The recommended steps are: first, sketch a rough layout, then map out the structure using HTML, and finally use CSS to style the layout.

What is the purpose of using IDs in HTML?

IDs in HTML are used to uniquely identify elements on a page, allowing developers to apply specific styles or functionalities to those elements.

How do CSS classes differ from IDs?

CSS classes can be applied to multiple elements to group and style them in the same way, while IDs are unique and can only be applied to one element.

What is the significance of using 'div' in HTML?

The 'div' element in HTML is a block-level element used to group content together, allowing developers to structure and style sections of a webpage.

What is the purpose of the 'span' element in HTML?

The 'span' element is an inline element used to apply styles to small sections of text or other inline content within a webpage.

How can IDs be used to create links within a webpage?

IDs can be used as anchors by placing a '#' symbol before the ID name in a link, which will scroll or jump the page to the element with that specific ID.

Why is it important to distinguish between block and inline elements?

It's important to distinguish between block and inline elements because they affect how content is displayed and organized. Block elements take up the full width of their container, while inline elements only take up as much space as needed.
