What is a container tag?
A container tag is a hypertext markup language (HTML) element used to group and contain other elements in a webpage.

Containers are an essential part of building well-structured and maintainable webpages.

How do container tags work in hypertext markup language (HTML)?
Container tags in HTML consist of an opening tag, which defines the beginning of the container, and a closing tag, which marks the end of the container.

What is the difference between block-level and inline-level container tags?
Block-level container tags, such as `, , and , create block-level elements that span the full width of their parent container. They start on a new line and stack vertically. Inline-level container tags, such as or `, create inline-level elements that flow within the text and do not disrupt the natural flow of content. They do not start on a new line and can be placed within blocks of text.
How can container tags be styled using cascading style sheets (CSS)?
Container tags can be styled using CSS to control their appearance and layout.

Styling container tags allows for consistent design choices across a website and helps in creating visually appealing and user-friendly webpages.
