Q & A

What is the primary focus of this tutorial?

The primary focus of this tutorial is to introduce HTML and CSS basics, particularly CSS selectors and styling techniques, by creating a simple webpage with articles.

What is the significance of using a 'style.css' file in this tutorial?

The 'style.css' file is used to separate the styling code from the HTML structure, following best practices for web development. It contains CSS rules that define the visual appearance of the webpage.

How is the HTML file structured in this tutorial?

The HTML file begins with a DOCTYPE declaration, followed by the 'head' section containing metadata like the title and the link to the CSS stylesheet. It includes 'body' elements with headings (H1, H2, H3), paragraphs (P), and other structural components.

What is the role of the 'link' element in the 'head' section of the HTML file?

The 'link' element in the 'head' section connects the HTML document to the external 'style.css' file. It allows the page to apply the CSS rules defined in that file to the HTML elements.

What CSS rule is applied using the universal selector in this tutorial?

The universal selector ('*') is used to apply a default font family to all elements on the page, ensuring consistency across the website.

What is the purpose of using a class selector, and how is it implemented in the tutorial?

A class selector is used to apply styles to multiple elements that share the same class. In this tutorial, the class selector is applied to the 'article' class, which is used for the titles of the articles in the webpage.

What is the difference between an ID selector and a class selector in CSS?

An ID selector targets a specific element with a unique ID, while a class selector targets multiple elements that share the same class. ID selectors are more specific than class selectors, and IDs should be unique on a page.

How does the 'span' element function in the HTML structure?

The 'span' element is an inline element used to apply styles to a small section of text within a larger block. In this tutorial, it is used to highlight specific pieces of information, like the author's name and date, within paragraphs or headings.

What is the effect of changing the font size using the 'H1' and 'H2' selectors?

Changing the font size using the 'H1' and 'H2' selectors allows the tutorial author to adjust the visual importance of the headings. For example, the 'H1' is set to a larger font size to make it more prominent than the smaller 'H2' and 'H3' headings.

What is the role of the 'first-child' and 'all-child' selectors demonstrated in the tutorial?

'First-child' is used to style the first element within a parent, while 'all-child' targets all child elements under a specific parent. These selectors help in applying styles to specific parts of the page, such as making the first paragraph under an H1 heading different from others.
