What is the primary difference between block and inline elements regarding content flow?
Difficulty level
Block elements cannot be nested inside inline elements.
Block elements start on a new line and take up the full width available, while inline elements do not.
Inline elements can contain block elements.
Inline elements can have margins and paddings.
Block elements, by default, start on a new line and occupy the full width of their container, pushing content before and after to new lines. In contrast, inline elements flow within the content and only take up as much width as necessary, not causing a line break. This characteristic fundamentally affects how they shape the layout and flow of content on a web page.
