HTML

• Hypertext Markup Language (HTML) is one of the three cornerstone languages used to develop webpages.
• The head element contains information about the webpage.
• The body element represents the visible content shown to the user.

CSS

• Cascading Style Sheets (CSS) is a programming language used by developers to define how webpage content is presented to users.
• CSS defines style rules for specific elements of an HTML page and formats them.
• A margin indicates how much space we want around the outside of an element.
• A padding indicates how much space we want around the content inside an element.
