HTML is the foundation of front-end web development. It stands for HyperText Markup Language, and is the language used to create webpages. HTML consists of elements, which are tags that are used to define the structure and content of the webpage. It’s the job of the HTML developer to use these elements to create webpages that are both visually appealing and functionally sound.
CSS stands for Cascading Style Sheets, and is used in conjunction with HTML to add visual styling to the webpage. It’s the job of the CSS developer to determine the font size, font color, background color, and other visual elements of the webpage. CSS can also be used to create visual effects, such as animations, and can be used to create responsive webpages, which automatically adjust to fit different screen sizes.
