1️⃣ How does the HTML5 concept of 'content categories' refine the traditional 'block vs. inline' model for developers?

  • A) It merges all elements into a single 'flow' category, removing all nesting restrictions to provide developers with greater layout flexibility.
  • B) It is an older, outdated system from XHTML that describes visual rendering, which has been replaced by the more modern 'block vs. inline' model.
  • C) It formally deprecates the 'block vs. inline' model, replacing it with a new layout system that relies exclusively on CSS for all structural placement.
  • D) It shifts focus from visual rendering to structural rules, defining where elements can be placed semantically.

2️⃣ What key behavioral difference regarding vertical padding distinguishes a standard inline element from a block-level element?

  • A) On an inline element, vertical padding only works if the box-sizing CSS property is set to border-box, otherwise it is completely ignored.
  • B) On an inline element, vertical padding is visually applied but does not affect the line height or push away content on lines above or below it.
  • C) Vertical padding on an inline element is completely ignored, just like vertical margin, having no visual effect on the element's background.
  • D) Vertical padding is fully respected on both element types, increasing the element's height and pushing away all surrounding content equally.

  • A) It is a mandatory requirement of the HTML5 specification.
  • B) Improves security by obscuring the full server URL path.

  • B) The <strong> tag for font weight and <em> for font style.
  • C) Using CSS properties like font-family, font-size, and color.
  • D) The <text> tag, which consolidates all font attributes.

5️⃣ What is the primary difference between the DOM and the HTML source code?
