HTML Summary

HTML(HyperText Markup Language) is used to define our page content, structure and meaning.
You don't it for styling purposes. Use CSS for that instead!

• HTML uses "elements" to describe (annotate) content
• HTML elements typically have an opening tag, content and a closing tag
• You can also have void (empty) elements like images
• You can also configure elements with attributes
• There's a long list of available elements, but you'll gain experience over time, no worries.

Learn more about all available HTML on the MDN HTML element reference.

CSS Summary

CSS (Cascading Style Sheet) is used for styling your page context.

• Styles are assigned via property-value pairs You can assign styles via the "style" attribute
• To avoid code duplication, you typically use global styles (e.g. via the "style" element) instead
• Alternatively, you can work with the external stylesheet files, which you "link" to
• When working with CSS, concepts like "inheritance", "specificity" and the "box model" should be understood
