Chapter 7. Bridging HTML and CSS
In this chapter, we'll explore how HTML and CSS work together to create structured and styled web pages. This chapter focuses on the key building blocks of HTML elements and CSS styling, including block and inline elements, how to nest elements, and global attributes such as class, ID, and style. We’ll also dive into creating interactive components like an accordion using the <details> and <summary> tags.
The following topics are covered in this chapter:
Block Element vs. Inline Element
We'll begin by exploring the differences between block-level and inline elements. Block elements take up the full width of their container and stack vertically, while inline elements only take as much width as necessary, allowing content to flow beside them. Understanding these distinctions is essential for effective layout design.
Nesting Elements – Parent Elements and Child Elements
In this section, we'll cover how HTML elements can be nested within one another, forming parent-child relationships. This structure is vital for organizing content and applying CSS styles efficiently. We'll look at how nesting affects the styling and behavior of elements in a webpage.
Div vs. Span
The <div> and <span> elements are both used to group other elements. The <div> tag is a block-level element, while <span> is an inline element. We'll compare when to use each tag based on their layout and styling needs, ensuring you know the best contexts for each.
Global Attribute – Class, ID and Style
We'll explain the global attributes of class, id, and style, which are fundamental for applying CSS. The class attribute is used to apply styles to multiple elements, while the id attribute is unique for individual elements. We’ll also discuss using the style attribute for inline CSS styling.
Accordion – <details> and <summary>
We'll explore the <details> and <summary> tags, which allow you to create collapsible content. These tags are perfect for adding interactive accordion-like features to your page, providing a user-friendly way to display hidden content.
