W3.CSS - Containers

HTML5 has the following container elements −

  • <div> − Provides a generic container to HTML content.

  • <header> − Represents the header section.

  • <footer> − Represents the footer section.

  • <article> − Represents articles.

  • <section> − Provides a generic container for various types of sections.

W3.CSS provides w3-container as a primary class to style all the above-mentioned containers. W3.CSS also has other classes like w3-border, w3-red, w3-teal, w3-padding-32 to add further styling attributes to the containers.
